Keira Knightley Keira Knightley has revealed a body secret.

She's been putting some graft into it.

And has now decided to open up and chat...

It seems Keira has become as famous for her tiny frame as her films.

And she's finally conceded she did at one point look "scrawny".

She told Glamour: "Now I work out once a week with this woman, who's great - I need a drill sergeant standing next to me to make me do things."

Her confession came after her own mum denied Keira was anorexic.

So now she's hired a personal trainer to bulk up.

Keira said: "Until this year, I've worked pretty constantly and I think you get to the point where you just need to stop for a minute.

"I hadn't worked out for about a year. A friend bought me a few sessions with a personal trainer for Christmas, so I've stuck to it.

"Before the trainer, I think I'd lost weight if anything. I lost muscle, so I looked scrawny. I don't know if it has changed anything, but it did make me feel good."

Gym'll fix it, eh Keira?
