Macklemore has joked he stares at his naked Justin Bieber painting to slow down his orgasms.

The 34-year-old rapper famously purchased artwork of the 'Sorry' hitmaker that features him using pancakes to cover his manhood on the online store Etsy last year, and has quipped that whenever he and his wife Tricia enjoy a love-making session he just takes one look at the picture on his wall to ''control'' the moment.

Appearing on 'Watch What Happens Live With Andy Cohen' on Thursday (16.11.17), the 'Thrift Shop' hitmaker said: ''I'm very proud of it, and it's become a huge headline. It's like, 'Macklemore owns a naked Justin Bieber d**k pancake painting,' and it's part of my thing now.

''So it goes right above my bed and whenever I'm with my wife intimately, I can always stare and if I want to control my orgasm, just slow it down.''

Macklemore was joined on the sofa by fellow rap star T-Pain who responded: ''I mean, that question has to be burned in his brain.

''If I had a picture of anybody with pancakes over their d**k, that would obviously be the start of the conversation.''

Meanwhile, Macklemore is set to become a father for the second time in the next few months.

The musician announced that Tricia - with whom he already has two-year-old daughter Sloane - is pregnant with their second child in a unique Instagram video.

In the clip posted in September, the 'Marmalade' rapper said the pair would be finding out the sex of their child on camera by cutting open a gender reveal cake.

Typically, gender reveal cakes contain blue frosting inside if the baby is a boy, and pink for a girl, however Macklemore played a prank on his fans when he instead pulled out a piece of paper, which announced he would be adding an additional date to his tour in his native Seattle.

He said: ''I woke up today, and I had an idea. You guys have been such a huge part of our lives, that I wanted to let you in on a little secret. Tricia is pregnant, and today we're going to find out the gender of our child.

''We're having a second night at Key Arena! Oh my god! Key Arena night two, tickets on sale tomorrow!''

The video then shared information about the extra show date, before Macklemore once again confirmed their happy news.

He added: ''Tricia really is pregnant though.''
