Actress Vanessa Hudgens is preparing herself for further embarrassment as fresh racy photographs are published on the internet.

The teenage star hit the headlines after confirming she posed for saucy snapshots intended only for the eyes of boyfriend and High School Musical co-star Zac Efron.

Hudgens was forced to apologise to fans after the camera phone pictures appeared on select websites.

But new images show the 18-year-old posing cheekily with pals and one shows Hudgens pictured cuddling up close to one of her friend's breasts. Other photos show her scantily-dressed.

A spokesman for Hudgens refused to comment.
