Pop star Justin Timberlake has branded his female fans "crazy" and admits they "scare the s**t" out of him.

The Sexyback star admits he is shocked by the lengths his admirers go to in order to sneak a peek at him - with many even hiding in his hotel room in readiness to pounce on the star.

But Timberlake - whose ex-girlfriend Cameron Diaz was 12 years his senior - insists it isn't just young women who frighten him.

He says, "I've had girls pop out of hotel closets. It scared the s**t out of me. That was in my teenage days. Teenage girls are pretty crazy. Actually, no - older women are crazy too."
