Jennifer Lawrence has said she sensed her career had changed once photographers and X-Men fans began stalking her to take pictures of her "in human form".
Jennifer, who has enjoyed Academy Awards buzz for her performance in Sundance Film Festival prize winner Winter's Bone, is now shooting her first big studio film - an X-Men prequel in which she plays shape-shifting mutant Mystique.
The day after she was cast, Jennifer and a friend were leaving her hotel when the photographers turned up.
Her friend asked, "'Who are these people here for?' and I was like, 'I don't know,'" Jennifer, 20, said in an interview at Hollywood's Chateau Marmont hotel, shortly before a reception to mark Tuesday's DVD release of Winter's Bone.
"And then they started taking my picture, and she goes, 'No way!' And I was like, 'No, definitely not. It can't be me," she went on. "Then we heard someone yell, 'Don't take pictures of Mystique when she's in human form!' We both looked at each other, and she goes, 'I am so happy I was here for that, because you are never going to live that down.'"
Jennifer also claimed Jodie Foster had reservations about casting her in black comedy The Beaver, starring Mel Gibson as a man who wears a beaver puppet on his hand. Jodie thought she might be too dark and edgy for a lighter story, Jennifer said.
"So first I'm flying overnight to prove that I look right for the role, and then I'm flying in to prove that I can be funny. And then, I think when Jodie met me, she went, 'Oh, she's an idiot. We're fine,'" Jennifer joked.
Unfortunately for the actress, her performance in The Beaver remains under wraps. The film's release is in limbo amid Mel's custody battle with ex-girlfriend Oksana Grigorieva, who claims he physically abused her.
Jennifer said she had a standard response to fend off questions about Mel's situation.
"I just try to say, 'It's sad,' while glaring at them, so they'll understand I don't want to talk about it," she said. "That's worked pretty well. I just blink less."
