According to sources, Vanessa Hudgens and Zac Efron have split.
While Zac was away in Europe promoting Hairspray, Vanessa was at a Hollywood Hills party, where eyewitnesses say she was "all over" her older, not-Zac date. And when someone dared to ask about Zac, Vanessa "threw a fit and said 'don't mention his name!'"

It was earlier reported that Zac would stand by Vanessa after her nude photos scandal.
