Presumably David Walliams could not be happier right now. He's probably suggesting a threesome as we speak. How bad.

Calvin Klein have decided to pair Justin Bieber and Lara Stone for their new Spring 2015 ad campaign. Apart from the addition of drums, which Justin is apparently playing, it's the usual Calvin Klein fare involving moody black & white footage of attractive sorts rubbing each other.

This isn't the first time Stone has encountered Justin in his pants; he opted to disrobe with her onstage during September's Fashion Rocks event. According to Lainey Gossip: "he stepped on stage to present with model Lara Stone, the crowd started hissing. In response, he took his shirt and pants off, then did a few lunges in his underpants. 'I actually don't feel comfortable unless I'm in my Calvins, is that cool?'" And an ad campaign someone got paid a wedge for was born...

If you'd find footage of Justin Bieber just hanging out in his manties solo more agreeable, this version of the underwear ad is for you. I'm not sure what he's got down there, but if that's all Bieber I'll eat my hat.
