Lindsay Lohan could get her probation revoked for allegedly lying to police when she said she wasn’t driving last June after her Porsche slammed into an 18-wheeler on the Pacific Coast Highway. But before heading back to LA yesterday to face the music, a bloated Lohan still managed to pull off what she does best — a night of partying. Lohan was spotted jumping behind the DJ booth at No. 8 Friday to play songs with the club’s resident spinner, Uncle Mike. “She played Marvin Gaye, Rihanna, Jay-Z,” said a source. Her Lifetime movie “Liz & Dick” will air Sunday, but her even less compelling court drama will certainly unfold sometime before then.
