Here’s Lindsay Lohan leaving her stripping pole-dancing class yesterday. She’s clearly holding a bottle of water, see, just in case she accidentally runs into a photographer. Water, not vodka. She’s taking the classes for her role in I Know Who Killed Me, about a young woman whose dual personalities were brought on by her brutal kidnapping. A source tells Marc Malkin at Planet Gossip that despite the exaggerated sexuality involved in her slithering up and down a pole, Linds will not be topless, but “is going to be wearing pasties.” No word on whether she’ll have on panties.
