Piers Morgan claims Kelsey Grammer walked off the set of his CNN show, "Piers Morgan Tonight," on Wednesday, moments before the star of Starz's "Boss" was to be interviewed.
"Kelsey Grammer was supposed to be on my show, but he ran out of the building. Strange," Morgan tweeted Wednesday.
Morgan later wrote, "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."
Stan Rosenfield, Grammer's publicist, told The Hollywood Reporter, "Piers needs to take responsibility for what he did to Kelsey. It's called accountability."
Kelsey and Camille Grammer divorced last year after 13 years together. She appeared on the first season of Bravo's "The Real Housewives of Beverly Hills."
Kelsey Grammer remarried in February 2011.
