We love it when the Biebs posts sexy selfies on Friday nights!

Yesterday Justin Bieber shared the above snapshot in which he's wearing a pair of Calvin Klein boxer briefs and grabbing his crotch and captioned the pics, “#mycalvins.” Well he IS an ambassador for the brand! And not only that, but according to a recent announcement from the brand's parent company PVH Corp., Calvin Klein outperformed revenue expectations for the first quarter of 2016 with a 13 percent increase in sales.

Earlier this year Calvin Klein, who sold his company 13 years ago, weighed in on the brand's celeb ambassadors. "I think the Justin Bieber thing is brilliant," Klein told CNN Talk Asia. "He's right on. Perfect for now."

We say perfect forever -- especially if his bod looks this bangin'!
