Wilmer's Revenge

Did Wilmer Valderrama raid the guest list for Lindsay Lohan's ``Saturday Night Live'' after-party, bringing mutual friends to a competing soiree? Our spies say the ``That '70s Show'' star lured Ashlee Simpson, members of the band Simple Plan and B2K frontman Omarito to MTV talent director Vinnie Potestivo's birthday party at Cellar Bar. And rather than heading to Rock Candy at 2 for Lohan's ``SNL'' bash, Valderrama's crew decamped for Suede, where they met up with JC Chasez, Seth Green and Taye Diggs. Christian Slater was one of the few celebs spotted at a Rock Center reception right after the show, but even he passed on Lohan's fete. Of course, he may have been having some technical difficulties. A snitch saw Slater in the men's room at Rockefeller Center having a private conversation with, well, his privates. ``Standing at a urinal and looking down, Slater queried, 'You can't do better than that?''' our source tittered.
