Justin Bieber Goes Nude On Instagram, But He's Not Pulling A Marc Jacobs With This NSFW Photo

The Biebs is having a moment in fashion in 2015. Actually, he's having quite a few of them, with many involving some degree of nakedness. Justin Bieber bared his butt on Instagram. Yes, he did. Don't all freak out at once, Internet! There isn't any full frontal action. But there is something to see here.

He's been twinning with Kris Jenner in a black and gold Balmain blazer, experimenting with a man bun, and flashing his chest in Calvin Klein ads. It's a fashion whirlwind and the style-conscious Bieber has moved on to full nudity. It's an image that will delight his female Beliebers, while leaving others wishing his rear end was something they could un-see.

The butt-baring Biebs posed with his back to the camera, while totally naked in front of a beautiful body of blue water. The latter is certainly secondary.

The Biebs wasn't pulling a Marc Jacobs with this NSFW shot. Jacobs admitted to accidentally flashing his derriere while flirting with someone online, whereas there is no mistaking that Bieber intentionally dropped trou (and everything else) for this shot.

You see a whole lotta of tattoos. And butt cheeks. But not much else. So it's artful pop star nakedness. You also get a glimpse of JB's little-seen Jesus tattoo, which lives on the back of his calf. I know you're thinking, "Who's looking at that?"

Who is The Biebs fist bumping? That mountain in the distance? A seagull in the sky? Sharks? Dolphins?

We get a lot of half-clothed JB on Instagram. He works out. He likes to show off dat body.

Getting a lift.

He also likes to show off those BA tattoos.

I can't deny he has some sculpted abs.

He's more shirtless than Marky Mark in his '90s, pre-Mark-Wahlberg-The-Actor heyday.

Boy II Man, like Boyz II Men, with whom he once collaborated.

Nice towel.

Oh hey Kendall and that smoldering stare.

This pose is familiar, if a little more clothed.

I am instantly reminded of Edward Cullen asking Bella "Doesn't he own a shirt?" in response to Jacob showing off his buff chest all day, every day in Twilight: Eclipse.

I think Biebs is just making a pitstop at fully nude. If his IG history is any indication, he'll return to posting shirtless-only shots in no time.
