It was a High School Musical reunion on the red carpet last night when Zac Efron and Vanessa Hudgens stepped out to support their pal Ashley Tisdale in LA. The party, which toasted the release of Ashley's Sharpay's Fabulous Adventures DVD, also marked the first time Zac and Vanessa walked the same red carpet since their split in December. Inside the event Zac and Vanessa were apprently friendly, but not affectionate. The two are apparently still friends after ending their five-year relationship, and it looks like Vanessa has already moved on with a new man. She's been spotted out with her Journey 2: The Mysterious Island costar, Josh Hutcherson, though she played coy about their status during a recent chat with Ellen DeGeneres. Whether or not there's a romance, Vanessa can help Josh celebrate the huge news that he scored the role of Peeta in The Hunger Games this week.
