Efron's 5-Year-Old Sister Joins His 'DWTS' Team, Becomes 'Second Best Dancer'

Just days before the upcoming "Dancing with the Stars" (DWTS) Dedication Night, actor Zac Efron, 33, has welcomed a new member to his team - his 5-year-old sister, Olivia. In a series of Instagram posts on October 12th, Efron shared glimpses of Olivia joining him and his partner Daniella Karagach, 32, for rehearsals.

Efron proudly introduced Olivia as the "newest member of Team DaDy" and noted that she has "quickly become 2nd best dancer on the team and by far the cutest." The actor shared sweet photos of Olivia on the dance floor, including one of her sitting in his lap while wearing ballroom shoes and another of her giving him a kiss on the cheek.

Ahead of the upcoming Disney Night performance, Efron gushed about Olivia's presence, telling Us Weekly that she gives him "more confidence every time I see her out here." He even revealed that his sister taught him a few dance moves "right before the show," calling her his "first dance lesson."

When Efron was first cast on this season of DWTS, he shared that his entire family, including his father David and brother Zac, were excited and supportive of his participation. With Olivia now joining the team, it seems the Efron clan is fully invested in Zac's DWTS journey.
