Justin Bieber is too sexy… for his pants. He is also apparently sexy enough for a role in the upcoming film adaptation of the best-selling erotic novel 'Fifty Shades of Grey.'

First things first. A photo of the Biebs grabbing his crotch, while wearing low-slung pants, was posted on Twitter. The Biebs is 18 now and his fans talk about Jerry (his name for his junk) so seeing a photo of the 'As Long as You Love Me' singer grab his stuff isn't exactly shocking anymore.

What is shocking, however, is the fact that the singer let it slip that he was offered a role in the incredibly sexafied film.

Hollywood Life reports that the Biebs told British talk show host Jonathan Ross that he has been approached to star in the film. He didn't reveal what role he would play. The lead role of Christian Grey could be it. Or not.

It'd be quite the adult part for someone like the Biebs. We're not so sure we could handle him being so mature and while on the big screen. This is one of those head scratching moments.

What do you think PopCrushers? Is a role in 'Fifty Shades of Grey' too mature for The Biebs? Most of his fans wouldn't be able to go see it!
