British royal Prince William has some explaining to do when he next sees girlfriend Kate Middleton - a picture of him seemingly feeling a girl's breast in a nightclub today features on the front page of a UK tabloid.

The picture, printed in The Sun, shows William standing with a pint of beer in one hand, with his other arm wrapped tightly around 18-year-old Brazilian student Ana Ferreira.

Ferreira and a friend had their picture taken with the 24-year-old royal after meeting him in a Bournemouth, England nightclub.

She says, "I was a little bit drunk myself but felt something brush my breast. I thought it couldn't be the future king, but now I've seen the picture it's no wonder he has a smile on his face. He has big manly hands and certainly knows what to do with them. It's a good job he had a beer in his left hand or he'd have had them both!"

Ferreira emailed the photo to her mother in Brazil.

She adds, "My mother thought it was very funny. She is pleased I met Prince William even though he was a little naughty."
