Justin Bieber, is that you?

Biebs might've taken down that photo of his naked bum, but that's not stopping him from getting a little racy in his latest S&M-tinged spread for Interview magazine. With an interview by Martha Stewart and photos by Steven Klein, the singer is featured in the mag licking knives, stripping down and wearing a creepy clown mask.

I don't know if I should be turned on or terrified.

Of course, as the official face of Calvin Klein's latest campaign, he's sporting some of their red undies in the shots. He's also wearing a leather, metal-studded mask and red gloves, his hair greased to the side.

In typical Bizzle fashion, he lifts his shirt to show of his glorious abs and goes sans-top for many of the photos. A bit of me also thinks he went sans-EVERYTHING in some photos…

The clown mask is essentially what will haunt our nightmares tonight, but these other sexy shots make up for it. In one, he tears off his top Superman-style (this summer is too hot for shirts anyway).

Also, it looks like he got one of those cup massages, or maybe it's another S&M tactic? Scary.

What do you think of Justin Bieber's new magazine photos?
