Justin Bieber is recovering ..

The Biebs followed in the footsteps of Ariana Grande -- no, not by licking donuts, by having his wisdom teeth pulled! JB bundled up, under the super hot LA sun, to grab some java with the hottie he calls his nurse, on Saturday.

The pair hit up Bouchon in Beverly Hills, Bieber hidden under a beanie, hoodie and Death Row Records jacket by The Hundreds. Of course he looked insanely cute and we couldn't detect much swelling. Guess nurse Micah held cold packs to those cheeks overnight!
