The 37-year-old singer - who has children Junior, five, and three-year-old Princess Tiaamii with ex-wife Katie Price - believes he is no longer as attractive as he used to be as he is starting to show the affects of ageing.

Asked to rate his attractiveness on a scale of one to ten, he said: "Less than it was. About a seven on a good day, six on a bad day.

"I don`t think I ever look really horrible, but I am noticing a few lines here and there.

"I`m Mediterranean, tanned and not as good as I was."

Despite his complaints, Peter is not afraid to show off his body by swimming nude.

He told heat magazine: "Have I ever been skinny dipping? Yes, many times. The last time was at home in Cyprus. I`ve done it jumping off cliffs."

The `Behind Closed Doors` hitmaker also confessed to liking to go out without wearing underwear.

Asked about his underwear, he said: "I`m not wearing any at the moment - I went freeflow today."
