Jeremy Piven leaving a yoga class at the Brentwood Country Mart in Brentwood (1/10)

Jeremy Piven went to a yoga class in Brentwood yesterday, and if his goal was to get the rest of the class to stare uncomfortably at his crotch wondering why he borrowed his nephew's sweatpants, mission accomplished!

Jessica Simpson (the hot version) on the set of The Dukes of Hazzard in 2005

Jeremy Piven really isn't that subtle. While Jessica Simpson was on the Entourage set earlier this week filming a cameo, Jeremy couldn't stop staring at her ass. Smooth dude, smooth. A witness told Us Weekly:

"In between takes, he was staring at Jessica's ass in the most obvious of ways," a witness tells UsMagazine.com. "He wasn't being sly about it and would just watch her every move. He flirts with ugly girls, so you can imagine how crazy for Jessica Simpson he was. She almost seemed like she couldn't wait to change into her jeans, but she was a good sport about it and kind of laughed it off."

You know what's most interesting about this story? If you replace "Jeremy Piven" with "Jessica Simpson" and "ass" with "catering truck," it still makes complete sense. See, watch:

"[Jessica] wasn't being sly about it and would just watch [the catering truck's] every move . . . Hector the cook started to get really uncomfortable. I heard him muttering something under his breath about 'el diablo' before he threw down his apron and ran out the back."

Jeremy Piven at a cafe in Brentwood (5/11)

Chris Kattan and Jeremy Piven got into it backstage at Alexa Chung's MTV show last Thursday. Why? Mercury poisoning of course. From the New York Daily News:

Kattan greeted Piven with a snarky, "So, what are you here to promote, your Broadway play?"

Piven, who famously dropped out of "Speed the Plow" in December, is in a legal battle with producers who believe the actor fabricated his [mercury poisoning] illness in order to get out of completing his contract, and was none too happy to be reminded of the incident.

Says an insider, "After some back and forth, Jeremy said something really personal to Chris that basically attacked his career. He said 'Whoa, man  -  I thought we were just fooling around here.' Jeremy slammed the green room door right in Chris' face, and about 20 people in the hallway outside could hear him yelling obscenities. He was furious.

"Chris felt really badly about the whole thing, so about 15 minutes later he tried to approach Jeremy again to apologize, to tell him he was just kidding and that he didn't mean to offend in any way. But Jeremy wasn't having it at all. He slammed the door in Chris' face AGAIN."

Jeremy Piven and Chris Kattan? Really? What, did they throw tampons and hit each other with their hair brushes? "Owie that hurt! Hey no fairs! Yours is made of wood!"

Hayden Panettiere at the 6th season premiere of Entourage in LA (7/9)

Remember last October when Jeremy Piven was hitting on Hayden Panettiere at an Emmy's afterparty, but she brushed him off? Nine months later, he's still trying to get into her pants. From the New York Post:

Jeremy Piven 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."

These two would be perfect for each other. Hayden likes older men and Jeremy likes women that are breathing. Further evidence that these two were made for each other: They both shop for clothes in the "Juniors" department, and they both list "acting" and "racing horses" as their hobbies. If Jeremy's serious about getting into Hayden's pants, there's only one thing he can do that's guaranteed to seal the deal. HINT: It rhymes with "three episode contract to appear on the next season of Entourage."
