Some East High Wildcats turned up to support Zac Efron's brother Dylan Efron in the Dancing With the Stars ballroom on Halloween Night. High School Musical star Ashley Tisdale shared a selfie with director Kenny Ortega as they attended the Tuesday, October 28, live taping of the dance competition. "I love @kennyortegablog so much," Tisdale, 40, wrote via her Instagram Story. "So much fun cheering on @dylanefron together." Dylan, 33, reposted the photo via his own Instagram Story on Tuesday night, adding a few crying emojis.
