Zac Efron, Vanessa Hudgens' friendly Hollywood outing

Exes Zac Efron and Vanessa Hudgens have each been spotted mixing and mingling around the Hollywood scene since their December split, but that hasn't put a damper on their friendly relations.


Arriving separately, Zanessa -- er, Zac and Vanessa, each came out to support fellow "High School Musical" alum Ashley Tisdale at her DVD release party on Wednesday (Apr. 6). As expected, onlookers are speaking up and weighing in on each and every interaction.

"Zac and Vanessa definitely seemed comfortable around each other," one tells Us Magazine. "They didn't seem affectionate or romantic at all, but they were totally relaxed and friendly."

Adds another, "They both came out to support Ashley. They knew they would both be there and were fine with it. They really are still friends."

And there you have it. Maybe next we'll get an Efron blessing on a Hudgens and Josh Hutcherson union. Or not. We're just wondering if Tisdale is mad that she was outshined at her own event, or if she's happy the DVD release of "Sharpay's Fabulous Adventure" is getting any recognition at all.
