'Transformer' actress Megan Fox is determined not to play up to her sex kitten image by refusing to agree to do nude scenes in movies for as long as she can.

Twenty-two-year-old Fox – who in 2008 was voted 'Sexiest Woman in the World' by FHM – is apparently not lacking any offers to take her kit off, though, but thinks it a better idea to hold back for a while so that she can work on creating a reputation as a serious actress who has talent.

"She's expected to strip for almost every movie," revealed an insider in the Daily Star.

"She must have had a dozen scripts come her way in which she plays a stripper.

"Megan's far from a prude when it comes to nudity. But she's aiming to keep her clothes on as long as she can."
