It can be quite easy to get competitive with your siblings – just ask any psychologist or Kardashian. And we’re sure it’s no different for the Jonas brothers; Nick, Joe and the other one. While it may seem that Nick is the most favoured, we’re not fully sold on that just yet.

Joe Jonas turns 30 today, and we’re looking over some evidence that would strongly suggest he’s the heartthrob out of the trio. Also, let’s not forget that he’s into a little BDSM, oh and he’s also got the biggest dick out of the group.

Check out the evidence below, and see more from that oiled-up GUESS campaign here.
