Lindsay Lohan

I guess I'm just slow to figure out this stuff. I just found out that Lindsay Lohan plays a stripper in her movie in current release.

That explains what's been going on. She's researching her role, it's just that the research got her so stoned that she didn't know the filming was over. It's the directors fault for not telling her that she'd finished the movie and could stop the research. It's not her job to know those things.
