Kelsey Grammer appeared on the Australian talk show ‘Sunrise’ the other day to talk about his hosting of The Australian Commercial Radio Awards and his new show ‘Boss.’

While they did talk about past shows like ‘Cheers,’ ‘Frasier’ and ‘The Simpsons,’ they also asked him about his ex-wife, Camille, and her stint on ‘The Real Housewives of Beverly Hills.’

It must be odd to appear on a talk show to plug a new project or some event that you’re going to be involved in, and then the hosts just want to talk about things that have happened in the past.

Sources say that Grammer wasn’t happy about the interview and went on a tirade backstage. It’s not clear from the video below that Grammer went on to rant and rave after the interview was over.

Perhaps, he didn’t like the question, but he stays calm and gives no hint whatsoever that he is irritated — at least not so irritated that he’d yell at the show’s producer backstage. According to unnamed sources, Grammer screamed, “You are a vile person. A sick dog. Your life must be tragic. I feel sorry for you.”
