The 20-year-old actress, who plays a shape-shifting mutant Mystique in the superhero prequel, appears naked apart from blue body paint in numerous scenes in the film and she was determined viewers would see her with womanly curves.

She said, “I knew that if I was going to be naked in front of the world, I wanted to look like a woman and not a prepubescent 13-year-old boy. I’m so sick of people thinking that’s what we’re supposed to look like.”

Jennifer is proud of her shapely figure and will eat whatever she likes, even though she knows it’s a rare occurrence in Hollywood. Speaking about her preparations for this year's Oscars, where she was up for the Best Actress Award for her role in ‘Winter’s Bone’, Jennifer said, “Around 15 minutes before, the guy doing my hair said, ‘If you can get a salad, get a salad’. I said, ‘I’m getting a cheesesteak’. I’m sure there’s proof on a hotel bill somewhere.”

Despite her new-found fame, Jennifer is still uncomfortable with being treated like a star. She told an American magazine, “When you are on set, everybody is like, ‘Oh, do you need water? Here are 45 bottles!’ It’s really bizarre. I’m still getting used to it. I’m still in wonderland.” ‘X-Men — First Class’ releases in India on June 10 in English, Hindi, Tamil and Telugu.
