Justin Timberlake is up for flashing his bum

Justin Timberlake is happy to show his bum off now – before he gets old.

The sexy singer and actor reckons he’s got another 10 years of bum flashing in movies before he’s likely to say no.

“I think that I am probably not going to be as game to show my ass when I’m 40 so I’ll probably do it now while I have less time to think about it,” said Justin.

“But I really don’t know what all the fuss is about. It’s no big deal. There was nothing really sexy about it.”
