The day before, Lindsay was spotted on the set of her upcoming film Scary Movie 5 with co-star Charlie Sheen.

The film is about three dancers — one veteran performer and two upstarts who are also best friends — who vie for the lead in a new production from a snooty, aloof, imperious, and oversexed director.
