Mark Wahlberg has revealed how he was alarmed to receive a picture from Justin Bieber of the pop star in his Calvin Kleins.

The actor famously modelled for the brand back in the 1990s - and his mantle has now been picked up by the Biebs.

But Marky Mark told E! News that he was less than thrilled when his successor gave him a sneak preview of himself in his own Calvins.

"He sent me a note saying he was doing it and I was like, 'Oh, cool', and then he sent me a picture and I was like, 'Dude don't send me a picture of you in your underwear'.

"That's crossing the line.

"I'll probably see it when I'm driving down the street, and I'll still try to avoid it."

Well if he doesn't want Biebs' saucy pics, we reckon there'll be plenty more volunteers.
