Keira Knightley is planning on shedding her clothes and posing nude soon, but unlike celebrities her age, Keira's doing it in the name of art.

Keira has reportedly been visiting London’s Halcyon Gallery to be painted naked by artist Mitch Griffiths for a new exhibition.

A source said: “It’s considered a great honor to be painted by Mitch. He is a highly respected nude painter and is painting as number of subjects for a new exhibition next year. He is delighted Keira decided to take part.”

Keira's one of the most beautiful actresses of her time, so we're sure it's just as big of an honor for Mitch as it is for Keira. We'll keep you guys updated with the portrait as soon as Miss Knightley sheds her clothes.
