So that's where he gets it!

Justin Bieber proved that good looks run in the family on Wednesday when he posted a black-and-white snap of his "swaggin" great-grandfather on Instagram.

Like his famous great-grandson, Bieber's dapper ancestor clearly had serious style -- he rocked a herringbone suit for the headshot. Even more striking is his resemblance to the 21-year-old pop star, particularly in the eyes and the chin.

Bieber has also been busy "swaggin" in front of the camera. The "Sorry" singer recently posted a photo from his most recent Calvin Klein campaign, in which he "flaunts" his fit physique in nothing but a pair of black boxer briefs.

With sharp looks like these, we wouldn't mind flipping through more of the Bieber family photo album!
