Keira Knightley graciously agreed to sign autographs for enthusiastic fans - while standing naked in a gymnasium-changing room.

The KING ARTHUR star, 19, was approached by a group of female admirers while in the nude at the Amida Health Club in Hampton, near London, and she signed their pieces of papers before getting dressed.

A source says, "These girls spotted her in the changing room and couldn't wait to go over to meet her, even though she didn't have her clothes on.

"Keira just acted like a true professional and got on with it.

"Word soon got round the club about what she'd done and no one could believe just how nice and down-to-earth she is that she didn't mind doing that."
