Eagles of Death Metal frontman Jesse Hughes says the provocative cover art for Zipper Down, the band's new album, came out of some old-school rock 'n' roll naughtiness. Hughes -- who leads the group with his childhood friend, Queens of the Stone Age's Josh Homme – confesses that "it was kind of a staged idea."

"Whenever you have an idea from me, it's going to have something to do with tits," he says. "There was a girlfriend of ours hanging out at the studio with the most amazing tits. I really just wanted to see them, that's honest-to-God how the album cover came up. We were like, 'No, really, this is the album cover design that we had from the get-go and we don't want to see any nudity, we just want to see some artistic nakedness.' So, whatever, it's just art. She went for it, and I was stoked."

So has Hughes ever been caught with his zipper down? "Yeah, when I was in third grade, I zipped my d--- in my zipper," he says. "I had to go to the ER. Just like in Zoolander (Editor's note: We're almost positive he means There's Something About Mary). Except not like that, I did not unzip it in, however he did that. That was one of the most interesting things that I've ever gone through in my life. [But] you know what? This is the kind of 'zipper down' that isn't 'caught with your zipper down.' It's more like a voluntary lifestyle choice. It's a lot easier to let s--- hang out if your zipper is down. Zipper Down is a phrase, like, relax. If someone is getting too excited, someone else will say, 'Come on, dude. Zipper down just a little bit.' Don't take s--- so seriously. Let it hang out."

Eagles of Death Metal are currently letting it all hang out on a world tour in support of Zipper Down, which will culminate with appearances at the Lollapalooza festivals in Brazil, Argentina and Chile in March.
