Teenage movie star Lindsay Lohan has reportedly stepped in to replace Scarlett Johansson in Tom Cruise's upcoming "Mission Impossible III".

Johansson pulled out of the picture due to scheduling conflicts and Lohan has allegedly been letting slip that she's the girl for the sequel, reports the Internet Media Database.

Lohan was overheard talking about the film during a yet to be broadcast interview. "Shhhh. You're the first ones I've told," she is quoted to have said.
