Justin Bieber left little to the imagination as he posed in nothing but his tidy-whities while on vacation with his wife, Hailey Bieber. The Grammy winner, 30, took to his Instagram Stories Thursday to share racy photos of himself after taking a cold plunge in his Calvin Klein boxer briefs.

Justin shared a sweet pic with Jack via Instagram on Wednesday, January 15, that showed the singer nuzzling the top of his son’s head. Justin’s eyes were closed in the black-and-white snap, which he featured alongside a carousel of images from a wintry family holiday.

In the snaps, Justin wore nothing but Calvin Klein underwear – a brand he was previously an ambassador for – as he sat outdoors with the beautiful snowcapped mountains providing a scenic backdrop. The singer was clearly keen to show off his lean physique and his extensive array of tattoos.

Wondering what Justin Bieber's up to? Thanks for asking, he appears to be on vacation in Aspen (much like every other celebrity this winter) and is spending his time shirtless, wearing just his Calvins,
