Fans of Breaking Bad still remember RJ Mitte as the heartfelt Walter White Jr., the young man whose cerebral palsy never defined him on screen or off. Behind that performance stood a tight-knit family, and many still ask the same question: who are RJ Mitte’s siblings? The answer is simple and meaningful. He has one younger sister, Lacianne Carriere, and their relationship shaped much of his life and career.

Who Are RJ Mitte’s Siblings?
RJ Mitte (born Roy Frank Mitte III on August 21, 1992, in Jackson, Mississippi) was adopted as an infant by Roy Frank Mitte Jr. and Dyna Mitte. The couple later separated, and RJ was raised primarily by his mother. His only sibling is Lacianne Carriere, born on February 17, 2004, in Lafayette, Louisiana. That makes her roughly 11 to 12 years younger than her brother.
There are no brothers or other sisters publicly known. Lacianne arrived after their mother had been told she could not have biological children following ovarian cancer. RJ has spoken openly about how her birth felt almost miraculous to the family. From early on, the two shared a household that faced real challenges, including their mother’s serious car accident that left her partially paralyzed for years. At just 13, RJ stepped up as the main breadwinner, taking odd jobs to keep the family afloat while caring for both his mother and his little sister.
The Special Bond Between RJ and Lacianne
The age gap never created distance. RJ often described Lacianne as “his baby” and treated her with a mix of big-brother protectiveness and genuine friendship. They bonded over cartoons, video games, and making music together. He took her to dinners and events whenever possible, and the two remained close even as Hollywood pulled them in.
Their connection was forged in difficulty. When their mother could not lift the toddler Lacianne after her accident, RJ filled that gap. He later said the experience turned him into something of a father figure as well as a brother. That sense of responsibility stayed with him. Long after Breaking Bad made him famous, he continued supporting his mother and sister financially and emotionally. In interviews over the years, he repeatedly returned to the same theme: family came first.
How Family Shaped Their Hollywood Journey
The move that changed everything was not driven by RJ’s ambition alone. In 2006 the family relocated to Los Angeles because young Lacianne had been spotted and offered work in film and commercial production. RJ came along to support her and, almost by accident, began taking acting classes for social reasons. Background roles, including on Hannah Montana, followed. Then came the life-changing audition for Walter White Jr.
The siblings’ paths stayed intertwined. Both pursued entertainment. RJ used his platform to advocate for disability representation and became a respected voice for people living with cerebral palsy. Lacianne built her own credits while growing up in the same industry. Their shared history of resilience—adoption, medical challenges, financial pressure, and sudden relocation—gave both of them a grounded outlook rare in Hollywood.
Lacianne Carriere’s Own Path in Entertainment
Lacianne has worked steadily as an actress, singer, dancer, and animal activist. Early appearances included episodes of Nickelodeon’s Victorious. She made her feature film debut in The Catch (2013) and later appeared in projects such as Triumph (2021), where she shared the screen in a family-linked production, and The Unseen (2023). She continues developing new work while maintaining a lower public profile than her brother.
