Kaitlyn Bristowe was totally starstruck seeing Zac Efron at Dancing With the Stars - just like Us. "I'm not gonna talk about the fact that I was probably making Zac Efron uncomfortable," Bristowe, 40, joked during the Thursday, November 20, episode of the "Dancing With the Stars Official Podcast" while recapping the Prince Night performances. Zac, 38, was spotted in the audience for the first time all season on Tuesday, November 18, cheering for his brother Dylan Efron and pro Daniella Karagach, who successfully secured a place in the upcoming finale.
