Kelsey Grammer decided, for whatever reason, that he didn’t want to be interviewed by Piers Morgan on his CNN show, and deserted the studio before any such thing could happen, reports The Telegraph.

“Kelsey Grammer was supposed to be on my show, but he ran out of the building. Strange,” tweeted the talk show host on Wednesday. The news seems to have offended Morgan, who himself cuts a ‘love or hate’ figure in the U.K. “So, Kelsey Grammer saw a photo of his ex-wife Camille in the open of our show and legged it. Extraordinary. Never had this happen before … I like Kelsey Grammer personally, but this was a shockingly unprofessional thing to do. I wasn’t even going to mention his ex-wife.” Grammer's publicist told The Hollywood Reporter: "Piers needs to take responsibility for what he did to Kelsey. It's called accountability." Seemingly embarrassed, and unable to let it go, Morgan continued to tweet about the Frasier star, saying "Relax Jimmy, unlike my guest Mr Grammer last night, I won't run away." He was referring to his upcoming appearance on Late Night With Jimmy Fallon.

The ex-wife Morgan was joking about may have had something to do with Grammer’s untimely exit (or timely, depending on who you ally with) although nothing has been officially released regarding what was said backstage. Grammer, 57, and Camille divorced last year before he married British flight attendant Kayte Walsh, who is 25 years younger than him.
