Actor Kelsey Grammer ditched CNN host Piers Morgan just minutes before he was supposed to be interviewed by him. The apparent cause: in the opening to “Piers Morgan Tonight,” there was a picture of Grammer’s ex-wife.

So, 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. #CNN

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

Tragically, Morgan did not respond by showing Grammer’s empty chair, as he did for Rep. Todd Akin a month ago.
