Lee Ryan wants to appear in a porn film.

The Blue singer - who has children Bluebelle, three, and Rayn, two, from previous relationships - is convinced he would be a "great" person to cast in a raunchy adult movie.

He said: "I'd love to do porn. I would! I think I'd be great. I'd be brilliant.

"I wouldn't stop though, that's the hard thing about being a porn star."

Lee - who met former fiancee Sammy Miller, the mother of his son Rayn, on social networking website MySpace - also admitted he thinks all his previous relationships have been "s**t" and doesn't think dating people in the same industry makes things any better or worse.

He added in an interview with Closer magazine: "There's lots to be jealous of in this industry - we're surrounded by beautiful women.

"I've been with people in the industry and not - and they both suck.

"It's just I haven't had one great relationship - every relationship I've had has been s**t."
