NEW couple alert: Jason Segal from CBS’s “How I Met Your Mother” had Chloe Sevigny of HBO’s “Big Love” on his arm during the HBO Emmy party in West Hollywood Sunday night. The duo drank Moët & Chandon champagne and ate Godiva chocolates and then “went outside together to smoke.” After they left the party together, another source spotted them “kissing and standing arm in arm” while waiting for their valet.

Thanks for that, Page Six, we’ll expect a nice fat check from Moet and Godiva any day now. And the next totally freakbag celeb couple, courtesy of our own personal gossip Patty Stanger, Female First,

Hayden Panettiere has sparked rumours she is dating ‘Entourage’ star Kevin Connolly.

The 20-year-old actress attracted attention on Sunday evening after spending the whole of the HBO Emmy Awards party holding hands and enjoying an intimate conversation with the 35-year-old actor.

A source is quoted as saying: “They were there to hang out together and stayed for hours until well after midnight. Kevin only left Hayden’s side towards the end of the night when he wanted to chat with someone at another table.”

This pairing makes a lot more sense, actually. Hayden can’t seem to be attracted to men who couldn’t conceivably have fathered her. And Kevin finally found the one woman in the greater Los Angeles area shorter than him. We heard their first date was sailing across a puddle on a leaf, Rescuers style, before having an enchanted picnic on a toadstool.

Hollywood cutie Drew Barrymore fell for ìEntourageî hottie Kevin Connolly on the set of their upcoming film, ìHeís Just Not That Into You.î But while Drew is looking for a serious romance, insiders tell The Enquirer that the happy bachelor just wants to have fun.

Drew, 33, and Kevin, 34, were spotted having drinks together at the Laurel Tavern in Studio City, Calif, on Dec. 21. While Drew poured on the charm with touchy-feeling gestures, Kevin played it cool and barely showed her any affection at all.

ìDrew was practically throwing herself at Kevin,î an eyewitness revealed. ìThey were at the tavern for almost two hours, and Drew was definitely the one initiating all the physical contact.î

It's pretty obnoxious that they're just assuming Drew is running after him because she is romantically into him. Personally we think she's just trying to chase him into a hollow log to capture him and make him take her to his pot of gold. Yar tar tar tar!

After a two-year romance, Nicky Hilton and Kevin Connolly have called it quits. "They're no longer a couple," a Hilton rep confirms exclusively to Us Weekly. Hilton, 23, began dating Connolly, 32, star of HBO's Entourage, in late 2004, just weeks after she annulled her three-month marriage to New York businessman Todd Meister. A Hilton pal says the heiress "dumped" Connolly on October 16 after she suspected he had been unfaithful. A rep for Connolly could not be reached for comment.

We think this whole infidelity thing is just a cover-up because Nicky is too embarrassed to admit that Kevin made off with her Lucky Charms. All of her hearts, moons, stars, clovers, horseshoes, pots of gold, rainbows, and red balloons–gone, never to be recovered.

ìOne partier told us: Brandon and Nicky decided to run around and call everyone a ëloserí or ëwhoreí – like the way other people call each other ísweetyí or ëhoneyí. î Connolly didnít like either word and when the oil heir wouldnít stop, Connolly ìsmacked him.î Davis, grandson of the late oil billionaire Marvin Davis, shrieked and cursed insults, prompting Connolly to ìpunch him in the face two times.î

And then Connolly received accolades and high-fives all around from main bros Drama, Vince, and Turtle, and the strains of a hip new song by rapper Saigon swelled, the foursome threw their arms around each other and pledged their allegiance to one another against the beautiful L.A. sunset, in a completely and totally non-homoerotic fashion.

"Entourage" star Kevin Connolly used his fist to defend the honor of girlfriend Nicky Hilton the other night at West Hollywood hot spot Hyde. Things got physical after pro skateboarder Chad Muska, who was guest-deejaying, made a lewd crack about the honey-haired heiress. "Kevin jumped into the DJ booth and hit Chad," a witness tells Us Weekly. "Chad tried to hit him back, but at that point they were separated [by security]." After Muska was escorted out the front door, another witness says Connolly "went back to his seat and continued to chat with Nicky."

We understand Connolly's stance here, as just gazing upon this picture of Chad Muska gets us a little punchy. He's like Stephen Dorff without the . . . uh, fame? Career? Class? Well, without the starring role in a Tara Reid movie, at least. Which reminds us of another Entourage catfight. Craft services must be slipping Alabama whup-ass powder into the donuts. What we don't understand is what Muska, someone who has been close enough to Bijou Phillips that he'll probably never be able to wash the skank stench off of his skin, could have possibly said about Nicky Hilton. Next to Bijou, Nicky is as pure and virginal as Hilary Duff. Oh shit.
