Justin Bieber shares ad shoot selfie with Mark Wahlberg

Actor Mark Wahlberg has revealed that pop sensation Justin Bieber shared a picture of himself in his underpants.

The 44-year-old actor was surprised when the singer sent a picture of himself in underwear though he did not ask him to, reported Ace Showbiz.

Bieber, 21, was excited as he was shooting for a Calvin Klein advert. The "Boyfriend" singer couldn't help telling the former face of Calvin Klein about it.

"(Bieber) sent me a note saying he was doing (the Calvin Klein ad) and I was like, 'Oh, cool,'. And then he sent me a picture. And I was like, 'Dude, do not send me a picture of you in your underwear. That is crossing the line,', the "Lone Survivor" actor.
