PIVEN’S MERCURY MELTDOWN

Looks like there’s more than a little truth to that Ari Gold arrogance. Jeremy Piven – who plays Hollywood super agent Gold in the HBO series Entourage – ruffled his feathers a bit during a September photo shoot for yesterday’s edition of New York Post’s Page Six Magazine. When asked to do a simple headshot, Piven said he could give “mediocre” and later proceeded to tear the sleeve off of a $350 Armani shirt. It could be on account because of Piven’s well-publicized bout of Mercury poisoning – that, or the guy is just a serious jerk.

KELLY OSBOURNE’s REHAB: ROUND 2

Sharon Osbourne has confirmed her daughter, Kelly, is going back to rehab. In other, more depressing news, the matriarch also mentioned a new Osbourne family variety show in the works for the venerable Fox network. If Ozzy were reached for a comment on either matter, we can only assume he answered incoherently.

JIM CARREY: AGAINST NATURE’S CALL

In light of Jim Carrey’s role in Sundance flick I Love You Philip Morris, Carrey recently commented on dealing with some inborn homophobia. When considering taking the part in a gay love story (opposite Ewan McGregor), Carrey said “there was a homophobic voice that rose up” inside of him, although he eventually got over it. To be fair, he also quibbed that he and McGregor had some “great sexual chemistry on screen.” Now that sounds like a real Yes Man.
