Can someone please tell Jeremy Piven that he is not actually Ari Gold? Sure it must feel good to finally be invited to the hot nubile young starlet's birthday celebrations, but they like you just the way you are, Piven, no need to put on the act all the time. Page Six has the story:

The "Entourage" party boy was wandering the beach in Malibu the day after attending Lindsay Lohan's 20th birthday blowout when several twentysomethings at a Smashbox Cares soiree offered him what appeared to be a "blunt" - a hollowed-out cigar filled with marijuana. "Piven gladly partook but then realized it had tobacco in it," says our bemused spy. "He launched into a tirade about how smoking ages you. He was with people in their 20s telling them he looked younger than them and took off his sunglasses so they could inspect his skin."

I know, I know, he has been all Zen and shit for a while now, but forcing a bunch of younger kids to inspect his skin, well, that just reeks of his Entourage egomaniac.
