Keira Knightley was so worried about her hairy legs she nearly turned down the cover of Vanity Fair.

The actress appeared nude in the raunchy photo shoot with Scarlett Johansson and fashion guru Tom Ford.

She told Access Hollywood:" We got there and they said:" Do you mind doing it in the nude? And we said:" What? I thought:' I can't I haven't shaved my legs.'

Knightley was only reassured when they promised to retouch the photo. She was thrilled with the finished photograph shot by legendary photographer Annie Lebiowitz.

The Oscar nominated actress said that she had great fun and it would be a great story to tell her grand kids. She said:" It was hilarious, I loved it. It makes me giggle every time I see it. I haven't had anyone come up and say they didn't like it. It's a mischievous streak coming out. Actually I think it is quite funny, I think it is something to show the grandchildren."
