Who Is Lauren Betts’ Sister?
Lauren Betts’ sister is Sienna Betts, a highly touted freshman forward for the UCLA Bruins. Born on October 3, 2006, Sienna stands at 6’4″ and brings versatility, scoring punch, and defensive instincts to the frontcourt. While Lauren (born October 15, 2003) is the 6’7″ senior center who’s a Naismith Award finalist and projected top WNBA pick, Sienna is carving her own path as a former McDonald’s All-American and multiple-time Colorado Gatorade Player of the Year.
The sisters grew up in an athletic household. Their father, Andy Betts (a former pro basketball player), and mother, Michelle Betts (a national champion volleyball player), passed on serious genes. They also have two brothers — Dylan and Ashton — making the Betts family a basketball powerhouse. Sienna committed to UCLA in 2023, intentionally choosing her own journey, but life brought the sisters together when Lauren transferred back to the Bruins. Now they’re teammates, not just siblings.
Their Incredible Journey from Childhood to UCLA
Basketball has always been a family affair for the Betts sisters. They played together as kids, often on Pop-A-Shot games where Lauren’s patience contrasted with Sienna’s energy. The family spent early years in Spain during Andy’s pro career, enjoying beaches and good food when not in the gym. Back in Centennial, Colorado, both sisters dominated high school hoops.
- Lauren won Colorado Gatorade Player of the Year in 2021 and 2022 before college.
- Sienna continued the streak, earning the award three straight years from 2023 to 2025.
- Both have excelled individually: Lauren as a defensive anchor and scorer; Sienna as a skilled power forward with great vision.
In 2025, they even landed NIL deals together with the Unrivaled 3×3 league. Their mom, Michelle, often gets mic’d up at games, cheering loudly — a perfect symbol of family support. Sienna made her UCLA debut in December 2025, and fans quickly saw the chemistry, including sweet assists between the sisters.
