Word is that during a photo shoot Jeremy Piven who was there to promote his play Speed the Plow, was a grade A asshole. This was even before he claimed his mercury poisoning from eating too much sushi. This is Piven’s remarks at the shoot.

“This isn’t my first time on the merry-go-round,” he said when asked to pose for a traditional head-shot. “You want mediocre? I can give you mediocre.” His pose? A DMV-worthy grin.

But, as you can see here, Piven didn’t want to give mediocre a little later. He popped his collar, and “letting out a guttural moan,” ripped the sleeves off a $350 Giorgio Armani shirt, the mag reports.

What a jerk! I like his role in Entourage, but stuff like this just makes me hate how big headed celebs get once they get their fame.
