Dylan Efron is turning Dancing With the Stars season 34 into a family affair.

Days before the show’s Dedication Night, Efron, 33, shared a glimpse of his and partner Daniella Karagach’s rehearsals alongside his 5-year-old sister, Olivia.

“Please welcome the newest member of Team DaDy, my lil sister Olivia,” Efron wrote via Instagram on Sunday, October 12. “She’s quickly become 2nd best dancer on the team and by far the cutest. Team DaDy-O. #DWTS.”

Efron shared a series of sweet photos of Olivia taking on the dance floor, including a pic of his sister sitting in his lap while wearing ballroom shoes. In one image, Olivia gave Efron a kiss on the cheek as he held her beside Karagach, 32.
