"Kelsey Grammer was supposed to be on my show now but ran out of the building. Strange," Morgan said via Twitter Wednesday.
"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," he tweeted. "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!"
But Grammer's representative issued a statement to TMZ blaming Morgan for the canceled chat.
"Piers needs to take responsibility for what he did to Kelsey. It's called accountability," the statement said.
