Welsh singer Charlotte Church fears her complaints about record company bosses sexing-up her image leave her open to accusations of hypocrisy as she made a "stupid and ridiculous" decision to pose for a best butt competition at the age of 16.

The former child star relaunched herself as a sexy singer in her teenage years but she has since claimed she was uncomfortable with her new image and is an outspoken critic of the industry's over-sexualisation of young girls.

However, Church now acknowledges her comments betray her "double standards" as she posed for Britain's Rear of the Year contest in 2002, but she still blames her advisers for not telling her to pull out of the competition.

Church tells British newspaper The Times, "It was sort of double standards in a certain way, because I did Rear of the Year when I was 16, which was a ridiculous choice, a stupid thing to do but, you know, there was a whole host of people that I was working with who should have said, 'Woah, woah, woah. You shouldn't do this. This is bad. You're 16, for f**k's sake.'"
