Liam Payne Really Did 'Strip That Down' For Hugo Boss Underwear Ad: See the Pics

Stella Maxwell is also featured in the campaign.

Liam Payne seems pretty excited to be part of the new Hugo Boss Hugo x Liam Payne bodywear campaign.

The "Strip That Down" singer nearly bears it all in the photos, which include shots of him lying in tight boxer briefs on a bed with Victoria Secret model Stella Maxwell lounging naked behind him, as well as another snap in which he appears to be totally naked with a topless Maxwell draped across his torso while she models a pair of Boss boxer briefs.

Payne recently spoke to GQ about his first nude shoot, saying, "Before we landed the deal with Hugo I’d gone into my gym and said, 'I'm going to get an underwear commercial.' I just wanted to do it; I knew I could do it. And then it actually happened! And I worked my ass off and I'm still hitting the gym: I didn't realise once you get on that thing you can't really turn it off."    

He also raved about getting go help design some clothes for Boss as well, and leaning on his friend Kim Jones -- the artistic director at Dior menswear -- who gave him some great advice. "It's the same as music: once you’ve had a hit you know what people want from you," Jones told him. "And I took that with me into the design meeting and used that to help the whole process. Find the hit and make it work." Mert and Marcus shot the campaign, which Payne said got "very raunchy very quickly." 

In fact, there was "a lot" of tequila involved in the shoot, he told the magazine, adding that the shots with Maxwell ended up being "a lot more naked" than he expected. "She as also naked. And I was just, you know, 'Don't look!'" he said. "She was naked behind me and I was thinking, 'Liam, don't look whatever you do." When he had to drop trou for a particularly revealing shot, Payne said he experienced a "real hollow moment" afterwards where he was outside smoking a cigarette thinking, "'I have basically just shot soft-core porn.' For one, my mum is going to kill me."

Payne's self-titled debut album is due out on Dec. 6. He recently released "All I Want (For Christmas)," the follow-up to his collab with A Boogie Wit Da Hoodie, "Stack It Up."
