We spotted Demi Moore at the New York City premiere of "Margin Call" last night. She was alone at the event, but her husband Ashton Kutcher is probably busy in Los Angeles filming his CBS show "Two And A Half Men." Either that or the gossip is true - the couple has split up.

Over the last few weeks the duo has been plagued by breakup rumors. Kutcher's alleged mistress Sara Leal recently spoke to US Weekly about a tryst with the actor.

Meanwhile, a moving van was recently spotted at the couple's home, and Demi may have consulted a divorce attorney. Other rumors suggest the actress has a substance abuse problem.
