Wanna see James Harden turn up and dance his face off at a dayclub party in West Hollywood? Well, here ya go!
The Houston Rockets superstar hit up Penthouse Dayclub on Sunday -- where stars like Diddy and Ja Rule were partying ... but all eyes were on Harden!
Harden was definitely the life of the party -- despite the fact someone busted out a coffin in the center of the club at one point.
Didn't kill the vibe though -- at the end of the party, our photog says Harden left the club with a whole lotta chicks .
