The 52-year-old singer was voted off the show last night (04.12.08) and despite insisting he didn't have a "game plan", claimed: "My work here is done."
He said: "Of course I'm disappointed. It's been a real rollercoaster for me.
I've gone hoarse I chatted so much.
"But I think my work there was finished. They don't need me interfering and messing with their minds."
David - who branded finalists Joe Swash, George Takei and Martina Navratilova "three nice guys" - insisted he hadn't manipulated other contestants and said it was "easy" to irritate glamour model Nicola McLean, who he repeatedly clashed with on the show.
He added: "I was real, I just reacted to people. Nicola gave me loads of currency. When she did something I just reacted to her.
"I wound her up to show people what she was like. She made it easy for me and helped me stay in so long."
He was described by his fellow contestants as "out for himself", "a snake in the grass" and "lazy" yet insisted he had done nothing wrong.
He explained: "I did say before I went in that I wasn't going to take any nonsense and I stuck to my guns."
David tipped former 'EastEnders' star Joe to win tonight's (05.12.08) final, before being reunited with his daughters Amber and Olivia.
