Kelsey Grammer says there are ''forces'' in his life determined to ruin his reputation.

The former 'Frasier' star claims there is only ''one source'' for all the malicious stories that appear about him online and he knows who it is but he refuses to name the person, although he has hinted it's his ex-wife Camille Grammer.

During a discussion about his desire not to speak about Camille in an interview, he told The Guardian newspaper: ''There are ... forces at work in my life these days that blast stuff out all over the internet. And there's only one source for these stories. And I'm not going to name her.''

The 58-year-old actor split from Camille in 2011 but only reached a settlement about custody of their children, Mason, 11, and Jude, eight, and their financial assets in December 2012.

Kelsey is now married to Kayte Walsh, with whom he has an eight-month old daughter Faith.

The 'Boss' star met air stewardess Kayte - who is 26 years his junior - on a Virgin Atlantic flight to London she was working on and he fell in love with her on their first date.

Kelsey said: ''She came out of the tube stop across from Harvey Nichols (department store), and I walked across the street from the hotel, and there she stood, and I just thought, 'That's the most beautiful thing I've ever seen.' And then we went for a walk in Hyde Park and snow began to fall. I looked at her, I kissed her, and we've been together ever since.''
