Justin Bieber has something to celebrate


We bet Justin Bieber is very happy with himself today – the singer has shot an underwear campaign for Calvin Klein, so it looks like all that posing with his top off has finally paid off.

The shoot is said to be released later this year (probably when all the news of the trouble he’s gotten into has died down).

We wonder will Selena be offering her congratulations to the singer after he neglected to wish her  happy birthday yesterday?!
