Justin Bieber: 'I have so many Calvin Kleins that I don't wear the same pair twice'

Canadian sensation Justin Bieber has revealed that he has so many pairs of underwear that he doesn't ever have to wear the same pair twice.

The heartthrob was announced as the new face of Calvin Klein underwear at the beginning of the year and he has now joked to James Corden, during an interview segment on 'The Late Late Show', that he gets sent so many briefs that he never has to wear a pair more than once:

"They send me a lot, boxes and boxes of Calvin Kleins... Yeah, I definitely don't wear them twice. There's so many."

Bieber, meanwhile, recently opened up about his new music in an interview with KIIS 102.7 and admitted that it's 'uplifting': "Overall I'm just really happy with the place I'm at, creatively. Uplifting music that people are going to dance to... it's a little different. I'm using my voice in my music, rather than out here in the world. Not really talking a lot, just using my music for that."
