Jeremy Piven -- Mama's Boy

He's a sneaky, backstabbing whiny little bitch on "Entourage," but when he's with his mommy, Jeremy Piven is a perfect little angel.

TMZ cameras spotted Ari Gold's alter ego walking arm-in-arm with his mother after dining at Nobu in Malibu last night, grateful the photogs were there to help light the way. A nice change from TMZ's last experience at the sushi spot!

Piven, who was reportedly banned from the Nobu restaurant in Aspen earlier this year, left on his own accord this time around. Boom!
