Sebastien LaSalle: The Los Angeles Child Actor Who Brought Luca De La Rosa to Life in The Cleaning Lady

Sebastien LaSalle is a young American child actor and model from Los Angeles, California, best known for playing Luca De La Rosa — the gravely ill young son at the emotional centre of FOX’s crime drama The Cleaning Lady — across the show’s first three seasons from 2022 to 2024. He shared the role with his identical twin brother Valentino LaSalle, a casting arrangement common in child performance that allows a production to manage the strict working hour limitations placed on child actors while maintaining continuity across a sustained role. Before he was old enough to begin school, Sebastien was already modelling for major national brands. By the time he was seven, he was a series regular on one of FOX’s most watched dramas. His story is, in its professional dimensions, a remarkable account of early talent — and it exists against a backdrop of circumstances that the family has had to navigate with courage.

Biography / Wiki Table

Early Life: Los Angeles and the Modelling Years

Sebastien LaSalle was born in Los Angeles, California, in 2014, one of identical twins — he and his brother Valentino are physically matched closely enough that they were able to share a single acting role across three seasons of a network television drama without the audience ever being aware of the switch. Growing up in Los Angeles, the city that is more thoroughly shaped by the entertainment industry than any other on earth, gave the twins early exposure to the professional world of commercial performance — and their parents recognised and supported their natural aptitude for it from a very young age.

Sebastien began modelling as a toddler, appearing in national print advertising campaigns for some of the most recognisable consumer brands in the United States — GAP, Nike, Honor the Gift, and Levi’s are among those documented in his professional profile. National print campaigns for these brands require child models of genuine photogenic presence and the ability to perform naturally and consistently in front of professional photographers, lighting rigs, and creative directors. Being booked for campaigns at this level, at toddler age, is not routine — it reflects both the twins’ natural charisma and their parents’ careful management of their early professional exposure.

Outside of professional work, Sebastien is a child with the kind of wide-ranging active interests that speak to a full and physical childhood alongside the screen career. He surfs. He sketches. He plays both drums and piano. He practises karate and Muay Thai — the latter a demanding combat sport that builds the physical conditioning and mental discipline that serve young athletes well across many areas of their lives. His twin brother Valentino shares several of these interests, including the martial arts practice, the musical instruments, and the modelling background — a natural consequence of growing up together and, in many ways, building the same professional life side by side.

What Is a Twin Cast in Television Production — And Why Does It Matter?

Before understanding the specific significance of Sebastien and Valentino LaSalle’s role in The Cleaning Lady, it is worth explaining why twin casting is so commonly used in professional television and film productions that feature young child performers.

In the United States, child labour laws — enforced by state labour departments and by industry union rules — place strict limits on the number of hours a child of any given age can work on a professional set in a single day. For the youngest children, particularly those under the age of six, these limits are very restrictive indeed — a toddler, for instance, may be permitted only a few hours on set per day, much of which must be rest time. For children between the ages of six and twelve, the limits are somewhat longer but remain considerably more restrictive than the working hours of adult performers.

For a production in which a young child character appears in almost every episode of a long-running drama series — as Luca De La Rosa does in The Cleaning Lady — scheduling a single child performer across a full production run without violating working hour limitations is nearly impossible. The solution is twin casting: two children, identical or near-identical in appearance, who can alternate across production days, each working only their permitted hours while the combined effort sustains the character’s full presence throughout the series.

This is not a new or unusual practice. Many of the most beloved child roles in television history have been played by twins — the practice dates back decades in American television and is a standard professional arrangement for child-heavy productions that require sustained character continuity.

For Sebastien and Valentino LaSalle, the arrangement meant that both boys were, in the formal sense, series regulars on The Cleaning Lady from its first season — each carrying half of a role that, from the audience’s perspective, appeared seamlessly continuous.

The Cleaning Lady: Luca De La Rosa and the Heart of the Show

Sebastien LaSalle and his twin brother Valentino were officially cast in the shared role of Luca De La Rosa in May 2021, when the production announced its initial series regulars alongside lead actress Élodie Yung (cast as Thony De La Rosa, Luca’s mother) and Adan Canto (cast as Arman Morales, the criminal who becomes Thony’s protector and partner).

The Cleaning Lady is an American crime drama developed by Miranda Kwok, based on the 2017 Argentine television series La chica que limpia. The series premiered on FOX on January 3, 2022, and centres on Thony De La Rosa — a Cambodian-Filipino former surgeon who comes to the United States on an expired visa, unable to return home because her son Luca requires a cutting-edge bone marrow treatment for a rare and life-threatening autoimmune disorder that is only available in Las Vegas. When the medical system fails to provide the treatment Luca needs, Thony uses her intelligence and resourcefulness to forge her own path — becoming a cleaning lady for organised crime in order to access the money, connections, and protection that keeping her son alive requires.

Luca is, in this context, the moral and emotional foundation of the entire series. He is the reason everything Thony does is done. He is the child whose illness gives the show its stakes, whose survival or death would determine the meaning of every sacrifice his mother makes, and whose innocence provides a constant moral reference point against the criminal world his mother has entered on his behalf. Playing this character — even at age seven, even as one of two children sharing a role — required a genuine screen presence and an authentic quality of childhood vulnerability that the audience would believe completely.

The LaSalle twins provided exactly that. The show’s official Twitter account acknowledged them directly in the early days of the first season, writing that Luca De La Rosa was “played by our cutest actors, Valentino and Sebastien LaSalle (twins)” — an acknowledgement of both their contribution and the warmth with which the production regarded them.

The Cleaning Lady ran for four seasons in total. Sebastien and Valentino appeared as Luca across the first three seasons, from the show’s 2022 premiere through the third season, which concluded in May 2024. In the show’s fourth and final season — which premiered on March 25, 2025 — the role of Luca was recast with a younger actor, Khalen Roman Sanchez, a change that generated some commentary from viewers who had followed the twins’ portrayal of the character across the previous three years.

The Cleaning Lady: Full Cast Context

The production in which Sebastien LaSalle built his acting career was a significant one by any measure — a major network drama broadcast on FOX, produced by Warner Bros. Television, with a cast of substantial professional calibre:

The show premiered to strong initial viewership and was renewed for a second season in April 2022, a third season in February 2023, and a fourth and final season in May 2024. It was cancelled in June 2025 after its fourth season concluded. The Cleaning Lady is available to stream on Max.

The production experienced a profound loss during its run when Adan Canto — who played Arman Morales, the show’s male lead alongside Élodie Yung, and whose chemistry with Yung was widely cited as central to the show’s appeal — died on January 8, 2024, at the age of 42, from appendiceal cancer. The third season’s premiere episode was titled “Arman” in his memory.

Timothy Busfield: The Legal Matter and Its Context

In January 2026, an arrest warrant was issued against Timothy Busfield — an actor and director who had directed six episodes of The Cleaning Lady during its run — on charges of criminal sexual contact of a minor and child abuse, involving twin boy actors from the production. The arrest warrant was issued by the Albuquerque Police Department on January 9, 2026. Busfield turned himself in on January 13, 2026, and has denied all allegations.

On February 6, 2026, Busfield was formally indicted by a Bernalillo County grand jury on four counts of criminal sexual contact of a child — all third-degree felonies under New Mexico law. He entered a plea of not guilty on February 10, 2026, and the case is expected to proceed to trial. He was released from custody pending trial in late January 2026.

Warner Bros. Television, which produced The Cleaning Lady, conducted its own independent investigation into the allegations before the arrest warrant was issued, and stated that the investigation was unable to substantiate the claims. The studio has confirmed it is cooperating fully with law enforcement. Busfield’s legal team has stated that the charges are completely false and that he intends to be exonerated.

The criminal complaint identifies the boys involved by their initials only, in accordance with standard legal protections for minor victims in criminal proceedings. The case is ongoing, and no verdict has been reached. Busfield has maintained his innocence throughout.

Hobbies, Interests, and Life Beyond the Camera

One of the most grounding aspects of what is known about Sebastien LaSalle as a person rather than a professional is the picture it paints of a child with a genuinely rich and active life outside of modelling and acting. He surfs — which, in a Los Angeles context, is both a common and a demanding outdoor pursuit that builds physical confidence and a relationship with the natural world. He sketches — suggesting a visual creativity that finds expression through drawing as well as through the performative channels his professional life has provided. He plays drums and piano, demonstrating a musical engagement that mirrors his twin brother Valentino’s own documented love of ukulele alongside shared instruments.

He practises karate and Muay Thai alongside Valentino — disciplines that build not just physical strength and coordination but the mental focus, respect for instruction, and controlled emotional discipline that are among the most useful qualities any young person can develop. These are not the hobbies of a child whose life has been entirely consumed by professional demands. They are the interests of a child living a full childhood alongside a professional career that began before he was old enough to remember its beginning.

He also does voiceover work — a dimension of the performance world that is, in some ways, the purest test of what a young actor has developed vocally and in terms of genuine character expression, since there is no physical presence to carry the moment, only the voice.

What Sebastien LaSalle’s Career Represents

The professional life of Sebastien LaSalle — to the extent that any meaningful assessment can be made of a child who is, as of 2025, approximately eleven years old — is a story of early talent meeting genuine professional opportunity, and of a family that has navigated both the rewards and the complexities of a child’s entertainment career with evident care.

His modelling career established him in the commercial world before he was old enough to understand what a professional booking was. His casting as Luca De La Rosa placed him in one of FOX’s most watched drama series at the age of seven, alongside lead performers of international standing, in a role whose emotional weight was central to the entire show’s moral architecture. His voiceover work demonstrates a professional versatility that extends beyond on-camera performance. And the range of hobbies and interests documented in his professional profile speak to a child whose life is considerably larger than his screen credits.

He is eleven years old. Whatever comes next — in his professional life, in his education, in the personal journey that the circumstances of the past years will inevitably shape in ways that cannot yet be fully known — he has already demonstrated something real and something worth watching. The quiet professional seriousness that the best child actors bring to their work was there in every episode in which Luca De La Rosa appeared on screen. That is the record Sebastien LaSalle has built. It is a meaningful one, and it belongs to him.
