ROBBIE WILLIAMS - WILLIAMS' SEX BOOK TO RIVAL MADONNA'S

Pop hunk ROBBIE WILLIAMS will rival MADONNA's infamous SEX book with his own tome - featuring images of himself completely naked.

The ANGELS singer wanted to show off his toned new body, so posed for the raunchy pictures at unusual locations in Los Angeles, mimicking the MATERIAL GIRL's notorious hitchhiker photo in one shot.

He explains, "I'm very comfortable with my body. I know I'll never be rail-thin or a super-hunk, but this is the best shape I've been in for years and I figured 'Why not show it off?'"

A source adds, "It's bound to make him a mint."
