Church is developing a more mature image

Alex Cowan, a spokesman for her record company Sony, said: "We are aware of the site and we looked at our legal options.

"It was put in the hands of our legal team - we do all we can to protect Charlotte."

Charlotte - reputed to be worth more than �12m since shooting to stardom as a schoolgirl soprano when she was just 11 - has sung all over the world and sold millions of albums.

More recently her fans have seen her turn from a fresh-faced schoolgirl into a young woman seeking a more sophisticated persona.

But she has denied trying to vamp up her image with figure-hugging dresses and make-up.

Charlotte: Her youthful image

She said: "I'm not trying to look sexier - I'm just growing up you know."

Charlotte, who lives with her parents in a seven-bedroom luxury house in Cardiff, south Wales, admits to having "three or four" boyfriends in the past - but "nothing too heavy."

She split up with latest sweetheart Max Hoare, 17, a few months ago after saying she was too young to have a serious boyfriend.

Fans found the website while searching for information about Charlotte's blossoming career.

Keen opera buff Mark Adams, 38, said: "It's very nasty. She's still a schoolgirl and should be treated like one despite being famous."
