Canadian Justin Bieber took some time to celebrate the birth of his adopted homeland Sunday, with a righteous wakeboarding sesh with his crew, while in Miami for a Purpose tour show.

Bieber staged one hell of an advertisement for CK, which he is one of the faces (and bulges) for, doing the damn thing while wearing only his tighty-whities.

Mmpf.

He wasn't shy about it on Instagram.

When he wasn't flaunting his supple ass and pelvic Hindenburg, Bieber was busy hittin' da club with rumored on/off again love(r), Dash Doll #1, who was in town with her kids and former publicist Jonathan Cheban, who Martha Stewart still doesn't know.

Happy Birthday, America!
