The `Behind Closed Doors` singer - who has children Junior, six, and four-year-old Princess Tiaamii with ex-wife Katie Price - has been receiving abusive messages from an unnamed person on social networking website twitter and the Australian star believes that he shouldn`t have to put up with the comments just because he is in the public eye.
He said: "I`ve been the victim of a twitter bully and last week I spoke out and asked the person spreading lies about me and my family to reveal their identity.
"This coward - whose twitter name I won`t reveal - is hiding behind a computer and doesn`t have the guts to say who they really are, but they`re more than happy to dish out abuse to me.
"A lot of people in the public eye are subjected to this kind of thing and I think it`s time we take a stand and bring these bullies down. As soon as I find out who it is, I`ll see them in court."
As well as the problems with his internet bully, Peter is also concerned about his father Sawas, who was taken ill on a recent holiday to Spain and is now staying with the star, along with his wife Thea.
Peter added in his latest column for new! magazine: "Dad`s out of hospital and he`s staying with me at the moment, but he`s got a really big operation next week. He`s having it done down in Somerset as there`s a specialist doctor in the hospital there who`s the best person for the job. I`m a bit worried about it, but I`m sure it`ll be fine."
