Disney star Vanessa Hudgens refuses to write in a no-nudity clause in her acting contracts - because she would consider stripping off onscreen as long as the film "calls" for it.

The High School Musical actress, 20, reveals she has no qualms about shaking off her squeaky clean reputation for good and getting naked for a movie role - but it will be a few years yet before her male fans can expect any titillation.

She tells Eonline.com, "I will show nudity in a film when the time is right.

"Right now, I wouldn't feel comfortable doing it, but if it's an amazing movie that I'm really passionate about and that's what it calls for, then we'll see."

Hudgens gave the world a sneak peek of what to expect when she hit the headlines in 2007 after nude photos of the actress leaked online. The full frontal snaps were reportedly intended for boyfriend Zac Efron.
