Kathy Griffin slams Mad Men star Jon Hamm

THE comedian has spilt the beans about why she really dislikes Mad Men star Jon Hamm. It all dates back to a star studded dinner party.

Comedian Kathy Griffin is not mates with Jon Hamm.

KATHY Griffin has blasted Mad Men star Jon Hamm in her new tell all book.

The comedian wrote in Kathy Griffin’s Celebrity Run-Ins: “You’ll never convince me to like Jon Hamm.”

“The vibe I’ve always gotten from him is cold and somewhat disrespectful … toward me. I’m suggesting he’s one of these hot guys who’s mildly funny but actually thinks he’s comedian-level funny.”

Most of Griffin’s issues with Hamm seem to stem from a star-studded dinner party hosted by talent agent Sue Mengers.

“So when Hammy showed up, too, inside I thought, ‘Oh great’. He even said to me, ‘What are you doing here?’ I said, ‘I earned my seat at the table. What are you doing here?’”

Griffin claimed that Hamm had a couple of drinks and rudely interrupted a conversation she was having with legendary actor Jack Nicholson.

“Hammy picks that moment … to start whispering boozy yammering into my ear,” she wrote.

“First it was, ‘You know your Emmy isn’t a real Emmy’. I let that one go, but then he whispered, ‘You’re so o-o-o-old.’

“Look, I’ve been told I’m old and not funny by a lot of guys — a lot of hot guys, too — but not when I’m in an intimate conversation space with frickin’ Jack Nicholson, an opportunity I figured I’d never get again; that’s the real reason I can’t stand Hammy. The double whammy of cruel but not playful comments and the horrible timing.

“Again, he’s not a comedian, folks. Hopefully done with the drink, but probably still Don Draper-y.”

Jon Hamm’s not the only star who cops it from Griffin in the book.

She claimed that Ellen DeGeneres has a “mean streak that everyone knows about,” and that Ashton Kutcher is “someone who’s made it perfectly clear to me that I have absolutely nothing to offer him during his precious time on earth.”
