Justin Bieber Instagram: Singer Takes an Icy Dip in His Calvin Klein Underwear [PHOTOS]

Justin Bieber took his no-shirt lifestyle international once again, baring nearly all. The 21-year-old posted a photo to his Instagram on September 22 on vacation in Iceland.

From the looks of it, he had just emerged from a swim in a gorgeous Iceland body of water, and while the photo’s background is incredible, Justin's fans would definitely appreciate his fit physique much more than the scenery.

“Glacier dip in #iceland,” the singer and underwear spokesmodel captioned a Tuesday Instagram shot in which he complements his body art and bleached mane with a white, minimalist pair of boxer-briefs.

The undies pic is one of several shots Justin is posting from his vacation adventure. On Monday, Bieber posed in front of a cross with his head in his hands.

It’s yet to be determined whether the Iceland trip is for work or play, but the Biebs seems to be enjoying the view, posting another shot by the water.

That's not the only time Justin has gone all Calvin and Abs for his Instagram followers. Last week, he posted another shirtless pic, from behind the scenes of his "What Do You Mean" music video.

His comeback single rings in its third week at No. 1 on the Billboard 200 chart.

Since dropping his latest single, Bieber has been everywhere. He performed what might have been one of his best performances yet at the Video Music Awards, he killed it on The Tonight Show and then he appeared on The Today Show— with platinum blonde hair! Now, apparently, he’s living it up in Iceland, going for swims and slowly killing the fandom.

Right now, the single singer is taking some time to focus on himself and his music — not his love life.

“I haven’t been in a relationship for a while now,” Bieber told Australian radio hosts Kyle and Jackie O during a recent interview. “I’m a relationship type of guy. I love to be in love, love cuddling. I love all that stuff,” he explained, adding, “I got my heart broken. I’m just trying to let that heal up.”
