Now Justin Bieber wants to be a Calvin Klein model... and shares the underwear shots to prove it

In the last month he has wanted to be a rapper, tried to be James Dean, and now, just call Justin Bieber Marky Mark.
Channelling the early career of Mark Wahlberg, the 20-year-old wants to go from pop star to Calvin Klein model.
Trying to prove he has what it takes to strip down to his smalls, the Baby singer posted two pictures of himself wearing the iconic underwear on Instagram.

Model behaviour: Justin Bieber showed off his underwear modelling skills on Instagram on Tuesday

Showing off his new tattoos - which have now spread to his right arm and chest - the star stopped short of stripping down to his black briefs, instead wearing a black and white shirt left open and a pair of low slung tracksuit pants.

Clearly the Canadian has been putting in the hours at the gym, as Justin sported a very impressive four-pack.
When the star first posted the image up on Tuesday he captioned one of the images, 'What if I do a Calvin Klein campaign?? Comment below yes or no'.
