Zac Efron and Vanessa Hudgens have called it quits, OK! Magazine insiders whisper.

Zac was away in Europe promoting Hairspray, while Vanessa was at a Hollywood Hills party, snuggled “all over” a much older date. Someone asked about Zac and Vanessa “threw a fit and screamed “Don’t mention his name!'”

A rep for Vanessa says the story is not true.
