There was a story the other day about Hayden Panettiere being a bitch on the red carpet. Now there’s another one of her being a bitch on the set of Heroes. According to OK! Magazine, Hayden, attempting to wield what little power she has, is trying to get her ex-boyfriend Milo Ventimiglia fired.

“She refuses to be on the set at the same time as him,” the pal tells OK!. “She is making it difficult for everyone involved.”

Since the split, Hayden has been linked to a string of men including rocker Anthony Kiedis, 46, her ex Stephen Colletti, 23, and Gerard Butler, 39.

You’d think Hayden would tread carefully. Ratings for Heroes have been on a steady decline since the first season and she’s not even the most popular character, but may be the most annoying. That Japanese guy who wiggles his nose has a bigger fan base than her. That is to say, it would be fairly easy to put a bullet in the back of her character’s head and ice Hayden for the rest of the season. Wink, wink.

Hayden Panettiere and Milo Ventimiglia, two people with the most difficult to remember last names in Hollywood, have split. Sources say it was a “lifestyle conflict,” making out with another guy usually is, and that they are in “very different places.”

The source tells Us that Panettiere, 19, “is young. She likes to go out in the Hollywood scene and that’s not his style.”

Ventimiglia, 31, “has been concentrating on work on his production company [Divide Pictures],” the source adds.

May-December romances rarely work. For one thing, they’re never old enough to get into clubs and for another, they always have to be home by ten to finish their algebra assignment.

I wasn’t sure how to spell his last name, so there you go. Anyway, previous reports indicated that Heroes stars Hayden Panettiere and Milo Ventimiglia (yes! got it.) were dating. There is no empirical evidence, but if they are, they’re probably not anymore. Radar Online reports that Hayden was “ALL OVER” (yikes, caps, must mean it’s really shocking) 21-year-old Jesse McCartney. RO writes:

And when we say ALL OVER [ed. note: again with the caps. what are you, 12?], that’s exactly what we mean. She was holding him tighter than Michael Phelps gripping that bong. The Heroes star was sitting on Jesse’s lap while he kissed her neck. Then she got up and did some crazy sexy dance in his lap.

Neck kissing? Sexy dances? Egads. Sounds like the devil was in Jesse’s pants. I hope they used protection. My mom says lap sitting leads to babies and babies are how God punishes the sinners.

Hayden Panettiere recently bought a $2.6 million house in West Hollywood, but her boyfriend/co-star Milo Ventimiglia isn’t happy. He thought they were going to buy a house together. In fact, he wants to marry Hayden. Star reports:

But it turns out Hayden isn’t ready to play house. According to the friend, she’s “freaking out” because Milo keeps talking marriage. Adds the chum, “She’s not even old enough to have a drink, so she’s not even thinking about settling down.”

Jesus, Milo. Calm down. She just turned 18. She still has to bang a bunch of dudes before she settles down. She hasn’t even gone to rehab, flashed her vadge or been arrested yet. Isn’t doing one of those a prerequisite in Hollywood for marriage? They’re like rites of passage. Don’t take that away from her and me.

It has long been suspected that Hayden Panettiere and Milo Ventimiglia have been and are currently dating. Last night at the Kira Plastinina US Launch Ace Gallery, the two made no effort to dispel that rumor. As you can clearly see, Hayden was all over Milo. As you can also see, Hayden was pretty surprised when Milo asked her to try anal. Noob, you’re supposed to just stick it in there.

Milo Vegetablegina Ventimiglia admitted to dating Hayden Panettiere when he toasted her at a pre-Christmas Water Grill party in Los Angeles.

“He called her his girlfriend and said that he loved her,” says an eyewitness. The insider adds that the couple spent the rest of the night holding hands.

Good for him. I hope when I’m his age I’ll be banging an 18-year-old actress every night too. I only hope their forehead won’t be as huge and they won’t look like a troll, but, hey, I’m not picky. My girlfriend, a mop with a wig, fake candy lips and huge cantaloupes for breasts (high five!), can attest to that.
