Dylan Efron says it was a "full circle" moment having brother Zac Efron in the Dancing With the Stars ballroom. "It means everything. I grew up watching him do stuff like this," Dylan, 33, told Entertainment Tonight on Tuesday, November 18, following the semi-final episode. "Looking over, my family's there, my girlfriend. Just seeing all of them together, that's my support." Zac, 38, made a surprise appearance in the DWTS ballroom on Tuesday, watching his little brother make it to the season 34 finale.
