Who Is Lauren Betts’ Sister?
Lauren Betts’ sister is Sienna Betts, a promising freshman forward for the UCLA Bruins women’s basketball team. Born on October 3, 2006, Sienna stands at an impressive 6-foot-4 and brings serious skill, athleticism, and court vision to the game. She joined her older sister at UCLA in the 2025-26 season after a standout high school career where she earned multiple Colorado Gatorade Player of the Year honors.
Sienna isn’t riding on Lauren’s coattails—she’s carving her own path while benefiting from years of friendly competition at home. The two sisters have always pushed each other, whether it was backyard hoops or intense driveway battles. Now, sharing the same college roster has added an extra layer of excitement, especially after UCLA’s recent national championship run where the sisters celebrated together on the biggest stage.
The Betts Family: A True Basketball Legacy
The Betts siblings come from serious athletic genes. Lauren, the oldest, was born in Spain while their father Andy Betts (a former pro basketball player standing 7’1”) was playing overseas. Their mother, Michelle Betts, was a national champion volleyball player at Long Beach State. The family later settled in Colorado, where all four kids—Lauren, Sienna, Dylan, and Ashton—grew up around sports.
- Lauren Betts: Dominant center and leader for UCLA, known for her elite defense and scoring.
- Sienna Betts: Rising forward with great versatility and high basketball IQ.
- Dylan Betts: A towering 7’3” high school sophomore already drawing attention from USA Basketball junior camps.
- Ashton Betts: The youngest sibling keeping the family active and supportive.
This athletic household has produced multiple top talents, with basketball running deep in their DNA. The parents’ divorce didn’t break the family’s unity—Michelle often handled the daily hustle while raising the kids, creating strong bonds among the siblings.
