The Pirates of the Caribbean actress, who bared all to film a bath scene with Sienna Miller in their 2008 movie The Edge of Love, shed her clothes during sessions at London's Halcyon Gallery for Mitch Griffiths.
A source told The Mail On Sunday: "It's considered a great honour 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 Kaeira agreed to take part."
Last year, the star demanded that promotional adverts for her 2008 movie The Duchess were left untouched after the shots for 2004's King Arthur were changed to enhance her breasts.
