LeBron James Turns Up At Drake Concert

LeBron James REALLY likes Drake ... and to prove it here's video of the best athlete in the world LOSING HIS FACE Wednesday night with Chris Bosh at Drake's Summer Sixteen concert in L.A.

We've seen Drake and LeBron actually share the stage when Drake performed in Ohio ... but this night LBJ was in full fan mode ... and you gotta see the progression of his fanhood in this video.

He starts off pretty mellow while Drake is performing "Summer Sixteen" but by the time Drizzy does "Child's Play," LeBron simply cannot control his groove anymore ... and goes full fan dance mode.
