Keira Knightley posing for nude painting

(HMG) – Pirates of the Caribbean actress Keira Knightley has agreed to pose nude for a well known UK artist. The English actress, has apparently been making clandestine visits to the Halcyon Gallery in London to pose nude for artist Mitch Griffiths.

“It’s considered a great honor to be painted by Mitch. He is a highly respected nude painter and is painting a number of subjects for an exhibition next year. He is delighted Keira agreed to take part,” a source tells The Mail on Sunday.

Keira, 24, obviously remains very happy with her modest figure and bared all in a bath scene with Sienna Miller in their 2008 movie The Edge of Love. She also demanded that promotional shots for her film The Duchess remain untouched after posters for King Arthur were altered to enhance her breasts and her advertisement for Chanel revealed hitherto unseen fuller breasts.
