Kathy Griffin ‘Never Forgave’ Jon Hamm for Interrupting Her Conversation With an A-List Actor

Kathy Griffin isn’t letting go of at least one grudge in 2026 — and it’s the one she holds against Jon Hamm.

Griffin, 65, revealed that Hamm, 54, once interrupted her conversation with Jack Nicholson, and she’s never forgiven him for it.

The incident happened at a salon party held by Sue Menger, and Griffin, along with other celebrity guests, were invited. The My Life on the D-List alum was excited that Nicholson, 88, recognized her and knew her name.

During the event, the Shining star also began discussing a topic Griffin was familiar with – James “Whitey” Bulger, a mob boss in Boston.

“He’s talking about playing a Whitey Bulger-type character, and Whitey Bulger had just been found and arrested after decades of being on the run,” Griffin said during a recent episode of the In Your Dreams With Owen Thiel podcast. “I’m thinking, ‘Oh my god, Jack Nicholson is talking about the one topic I would want to ask him about.’”
She went on to say that the former Mad Men star took her attention away from the conversation and claimed he was “wasted.”

“So he’s next to me in my ear, and he’s going, ‘You’re so old. What’s it like to be so old? Your Emmys are fake Emmys,’” Griffin continued. “And I go, ‘No, no, Hammy. And you don’t even have an Emmy.’ But I never forgave Hammy for that.”

The longtime comedian also admitted that there was another reason Hamm was on her “hit list.”

“Like, nobody hates Jon Hamm except me,” Griffin said. “And it’s so funny. Because I used to date a guy that was in his fantasy football league, and I thought Hammy was rude to my boyfriend. I just thought, ‘Ooh, that shows bad character.’ Even though he’s an amazing actor and I hate to admit it, he’s even funny. And hot. Of course he’s hot.”

Hamm has not addressed the incident as of now.
