TMZ is reporting that Kelsey Grammer wasn’t feeling too cheery last night after he allegedly stormed out of CNN’s New York studios moments before he was scheduled to sit down for an interview with Piers Morgan.

The reason: Grammer saw a photo of ex-wife (and Real Housewives of Beverly Hills) star Camille Grammer displayed in the intro, and abruptly left.

Morgan took to Twitter to explain what happened: “Kelsey Grammer was supposed to be on my show now but ran out of the building. Strange.”

Morgan followed with more tweets: “Kelsey Grammer saw a photo of his ex wife Camille in the open to our show and legged it. Extraordinary. Never had this happen before.”

“I had a very friendly chat with Kelsey backstage. He said he was really looking forward to the interview. Weird.”

“I like Kelsey Grammer personally, but this was a shockingly unprofessional thing to do. I wasn’t even going to mention his ex-wife!”

On the flip side, a rep for Grammer released a statement addressing the bizarre incident, and said: “Piers needs to take responsibility for what he did to Kelsey. It’s called accountability.”
