Perhaps Diddy's plan to create a celebrity chauffeur service wasn't such a bad one after all. After leaving a club last night mumbling and grumbling, beach yogi Jeremy Piven made an attempt to drive himself home in a techno-blaring first generation Ford Bronco (we think), but didn't make it very far. Seems the services of his dealer friend were needed to act as designated driver and deliver the Pivster to his abode unharmed. But what went down at the gas station where he abandoned his machismo-exuding ride? Tell us, nicotine-addicted witnesses, do tell us!
