Frasier star Kelsey Grammer fled from a New York television studio just moments before he was due to be interviewed by Piers Morgan.
Morgan suggested on his Twitter page that the 57-year-old actor became uncomfortable when a photograph of his ex-wife Camille was aired at the start of the show.
Morgan later tweeted that he hadn't intended to ask him about his divorce from Camille.

- Their divorce was finalised in February 2011 and Grammer later joked that they hadn't had sex for a decade before the split
- The couple are going through a legal battle for custody of their two children
