JEREMY PIVEN OGLES HAYDEN PANETTIERE

JEREMY Piven (above) seemed fully recovered from mercury poisoning at Thursday night’s “Entourage” premiere in LA. Spies at the Belvedere-hosted soiree on the Paramount lot told us, “Piven was looking Hayden Panettiere up and down in between sips of vodka and soda.” The 19-year-old “Heroes” starlet was with Alexis Dziena, who was in one episode of the HBO show, while Jamie-Lynn Sigler cuddled with beau Jerry Ferrara, who plays Turtle.
