Oscar-nominated actress Jennifer Lawrence recently sprung our Winter’s Bone while talking to the press about being naked as seven girls apply the blue body makeup needed to transform her into a young Mystique on the set of X-Men: First Class.

She tells THR:

Nothing’s sacred anymore. Those girls and I got so close. They were painting me naked every day for months. It was kind of like going to a really bizarre sleepover. It’s what you guys imagine we do: One naked girl and seven pairs of hands all over her.

Lawrence stars in the Oscar nominated indie-drama Winter’s Bone and will headline A Bigger Boat’s upcoming thriller House at the End of the Street.

X-Men: First Class is an origins story directed by Mathew Vaughn (Kick Ass) for 20th Century Fox. The film costars January Jones (Emma Frost), Rose Byrne (Moira), Kevin Bacon (Sebastian Shaw), James McAvoy (Charles Xavier), and Michael Fassbender (Magneto).
