Kelsey Grammer "ran out" on an interview after seeing a picture of his former wife. The former Frasier star was due to be interviewed by Piers Morgan for CNN's Piers Morgan Tonight but became so uncomfortable after seeing a photograph of his ex Camille Grammer that he left the building before filming began.

"Kelsey Grammer was supposed to be on my show now but ran out of the building. Strange. #CNN 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 (sic)," Piers wrote on Twitter.

When Piers' former America's Got Talent co-star Simon Cowell responded by saying "I know how he feels," Piers joked it was possible Simon's new show The X Factor which scared him off. "I suspect Kelsey was watching X Factor in the green room and suddenly felt nauseous," he wrote.

However, when the music mogul offered to intervene, tweeting "if he was watching x factor he wouldn't have done a runner. Do you want me to call him for you?," the chat show host was quick to respond, "Yes please."

The 57-year-old actor has previously launched a number of verbal attacks against Camille - with whom he has two children, daughter Mason, 10, and seven-year-old son Jude - recently, saying their marriage was over almost as soon as it began and he only stayed with her out of obligation.
