Charlotte would not embarrass her family by baring all

The Welsh singing star said she was approached at a showbiz party soon after becoming famous.

"When I was 13 someone came up to me at a big celeb do and said, `Do you want a line of coke?' At 13!," she told a TV magazine.

Cardiff-born Church, now 18, said she was still shocked by the memory and insisted: "I'd never do drugs."

The teenage soprano, who inherited a reported £16 m fortune on her last birthday, revealed the story in an interview with the Radio Times.

She also admitted she had considered stripping off for a men's magazine, but was talked out of it by her mother Maria, who has always been conscious of protecting her daughter's image.

"They were offering me ridiculous amounts of money," she explained.

"I said to my mum, `If it gets really ridiculous and they start offering me hundreds of thousands, I'll have to do it'.

"And she said, `Don't you dare! Your Nana will go mad if she sees you half-naked in a lads' mag.' So no, I couldn't do it."

The child star-turned pin-up added : "It's not that I think there's anything wrong with it. Loads of women do it, and they look gorgeous.

Maria Church guided her daughter's career

"It's just the way things are going. You have to show a bit to get anywhere these days.

"But there's no way I could do it. It's not just my Nana - my Grandpa would see it and my dad, and all my dad's friends. There's just no way it could happen."

Church used the interview as an opportunity to defend her mother, who has been portrayed in a poor light by some sections of the media.

"Everyone has this picture of her as this crazy psycho bitch who's pushed me all the way," Church explained.

"But really she's just a feisty, passionate woman who's determined that no-one will take advantage of her daughter."

Mother and daughter fell out over the relationship with former lover Steven Johnson.

Church said she now realised her mother was right and that she "went off the rails" for a while.

She admitted to sneaking off to see him in the middle of the night by climbing out of her bedroom window into a taxi.

"I felt that there was no-one, bar him, who really cared for me, and that forged a bond. But that bond's broken now, thank God," she said.

She now has a new boyfriend, who lives close to her home in Cardiff.

"Everyone thinks that because I have all this money and stuff, I should only go out with people who are rich. But I know the boys I like," she said.

"I've been brought up a working-class girl and I don't expect I'll ever be anything else."
