Much like his character on the Starz series Boss, veteran actor Kelsey Grammer likes to be in control. It's a lesson that Piers Morgan learned the hard way Wednesday night. The 57-year-old Emmy-award winner was set to sit down with the CNN host when things quickly went awry. According to multiple media reports, producers flashed a photo of Grammer's ex-wife Camille at the start of the show. The move didn't go over well with Grammer, who obviously has strong feelings for the former Real Housewives of Beverly Hills star. And not the good kind either. Right after they put Camille's mug on display, Grammer hightailed it out of the studio without warning, leaving Morgan guestless. An emotional Morgan took to Twitter to express his shock with Grammer's behavior. Morgan Tweeted, "Kelsey Grammer was supposed to be on my show now but ran out of the building. Strange. 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. I like Kelsey Grammer personally, but this was a shockingly unprofessional thing to do. I wasn't even going to mention his ex-wife!" Grammar has been hitting the media circuit hard lately, and on several occasions used the public platform to take digs at Camille, with whom he has two children. Of course, Grammer's rep believes it's Morgan who owes the former Frasier actor an apology. His rep released the following statement over the incident: "Piers needs to take responsibility for what he did to Kelsey. It's called accountability."
