No Threesome For Lohan, Knightley & Some Dude

If you were wondering why Lindsay Lohan didn't head from Tokyo to London to begin filming "The Best Time of Our Lives" co-starring Keira Knightley, it's because Knightley didn't want that stinky va-jay-jay in her face.

Not really, but Lohan's not a part of the project anymore according to Life & Style mag:

A source told the mag, "She didn't back out and producers didn't pull the deal, but there were changes that weren't to her liking, and that was that."

Lohan and Knightley were rumored to be part of a steamy threesome in the film. I'm blaming it on three things: 1) Lohan's nasty cooter...2) Rumored girlfriend Sam Ronson was jealous...& 3) Lohan didn't want to make out with a beanpole.
