Lordy, that's a lot of frontage... Remember a few months back they released photos of Calvin managing to model items of clothing while topless? Well, now it's time for the underwear campaign. Brace yourselves. 

And, from a slightly different, eh, angle...

If it's just the no nonsense full frontal you're after...

To be honest, the last person I'm thinking about right now is Justin Bieber, but that hasn't stopped twitter drawing comparisons...

The ONLY comparison is that, a couple of years ago, you probably wouldn't have been pressed to see either of them in their manties.
