Justin Timberlake thinks body odor is sexy.

The singer-and-actor - who is dating actress Jessica Biel and has previously romanced Cameron Diaz and Britney Spears - loves the natural smell of a woman, so long as it isn't too overpowering.

He told Cosmopolitan magazine: "Some people say BO (body odor) can be an aphrodisiac and I agree. It depends on the body the odor is coming from. It's a long-term intimate thing.

"You don't want it to be the first thing you smell when she comes into the room. It's about layers - layers meant to be discovered."

The 'SexyBack' singer also likes women to wear perfume that smells of sweet food as floral scents can be overpowering.

He added: "Men like scents that have more to do with food than roses. Something subtle and not too loud or overt.

"A woman doesn't need something whimsical to be sexy - smart is sexy. Sleek is sexy."
