Obama Jams Out to 'Hotline Bling,' What Happened to Kendrick?!!

Prez Obama SAYS Kendrick Lamar would kick Drake's ass in a rap battle, but our leader showed some serious Canadian love Saturday night at The White House.

Obama co-hosted "Love & Happiness: A Musical Experience" with BET.

A paparazzo was in place at 1600 Pennsylvania Ave to record the whole thing ... Usher.

Who knew being President could be so much fun.
