The Mean Girls star, who was approached to fill Scarlett Johansson's shoes by director J.J. Abrams, confesses she's limping after injuring herself while training for the part.
Lohan says she has been contacted about the proposed role since sustaining the injury. She tells Web site IGNFilmForce.com, "I did get a trainer, but I have a sprained an kle right now, so it's very hard for me to get back and forth to the gym.
"I don't know what's going on with (Mission: Impossible 3). We'll see."
Lohan is also keen to play down reports she's getting ready to star in a Barbarella remake, insisting she merely wanted to dress up as Jane Fonda's most famous character for a photo shoot - but she wouldn't turn down the role if a remake was offered to her.
She adds, "That would be hard to make. That would make me nervous. It's a classic... I'd be honored."
Brad Pitt was dismayed to discover photos of his Kenyan beach holiday with alleged lover Angelina Jolie earned a persistent photographer in excess of $500,000--because the money could have been much better spent.
In an explosive and candid interview with Diane Sawyer on Primetime Live, which was broadcast June 7, the movie hunk admits he would have set up the shots himself if he knew the snaps would be so lucrative.
He told Sawyer, "It's amazing, the bounty that is on my head and the lengths that these people go to to get these shots, and the amount of money that they're paying for these shots.
"It's something like half a million dollars or three quarter of a million dollars for the shots.
"I can't help but think what that money could have gone to. Hell, I would have set up the damn pictures myself."
Meanwhile, Pitt is known as Dabbo in the Ethiopian village where he's become a father figure to kids hungry to learn--because locals are convinced he's called Bread.
