Piers Morgan: Kelsey Grammer 'ran out' on interview over Camille Grammer photo

Moments before Kelsey Grammer was to appear on CNN's "Piers Morgan Tonight" Wednesday (Sept. 19), he "ran out of the building," Morgan tweeted .

Why? According to Morgan, "Grammer saw a photo of his ex wife Camille in the open to our show and legged it."

"I wasn't even going to mention his ex-wife!" the British talk-show host added about the "Real Housewives of Beverly Hills" star.

Noting that he'd never had a guest walk out on an interview before, Morgan called the "Boss" actor's exit both "extraordinary" and "shockingly unprofessional."

He was even more surprised because the two shared "a very friendly chat" backstage. "He said he was really looking forward to the interview," Morgan wrote, concluding: "Weird."

Guess that picture wasn't worth a thousand words?
