Vanessa Hudgens is adamant she is not jealous of her boyfriend Zac Efron's legions of adoring female fans - because she understands exactly how they feel.

The High School Musical co-stars have been dating for nearly a year, and Hudgens admits she often feels like a giggly, teenage fan when she is around him.

She says, "It's all good with Zac. I don't get jealous - not at all - when Zac gets loads of attention. I do, too. And I don't mind if girls scream at him - I like to scream along too."
