Vanessa Hudgens would appear nude in a movie – but only if the role required it.

The High School Musical star would happily strip off on screen but wants to wait until she’s older as she doesn’t feel ready yet.

The 20-year-old actress, who is dating heartthrob Zac Efron, said: “I will show nudity in a film when the time is right. Right now, I wouldn’t feel comfortable doing it.

“When the time’s right, if it’s an amazing movie that I’m really passionate about and that’s what it calls for, then we’ll see.”

Although she doesn’t feel it is appropriate for her to strip off now, explicit photos of Vanessa have already been seen.

In September 2007, pictures of her posing provocatively in lingerie were leaked on the internet, as well as one naked shot.

She later apologized for the images, saying she was “embarrassed over the situation” and regretted having “taken those photos”.

A statement from Disney - who make the High School Musical movies - said: “Vanessa has apologized for what was obviously a lapse in judgment. We hope she’s learned a valuable lesson.”

Jennifer Aniston has reportedly turned down a $4 million dollars offer to pose nude for Playboy magazine. This idea came to Hugh Hefner after Jennifer Aniston posed for GQ magazine in just a neck tie.

Speaking of the photos, Hefner said: “This looks like the cover of Playboy. I’m much impressed by Jennifer. Is it just me or is Jennifer Aniston getting hotter?…Never seen her in this light before.”

Hugh said she could make up to $10 million as a reward for high sales, but Aniston still said she had no intentions to take off her clothes and pose naked for his magazine. Jennifer Aniston does not need Hughs lousy $10 million, she has Friends under her belt.

The photo was from 1985 before she was famous and at the age of 20. A full frontal black and white picture of Madonna will be going on sale at Christie’s auction house February 12th. The photo was taken by Lee Friedlander after Madonna answered a newspaper advertisement looking for a nude model. It is reported that she may have only earned $25 bucks and now the picture will start off at $10,000 at the auction. It is pretty crazy to think that Madonna went from nude modeling to a world famous pop star.
