Chris Brown -- Guess Who's Coming to the BET Awards After Party?

You might think Chris Brown would be persona non grata at the official BET Awards after party tonight, but TMZ has learned the nightclub combatant was indeed invited and RSVP'd yes.

According to our sources, CB will be in attendance at the star-studded soiree going down at Playhouse in Los Angeles ... where Usher, Common, and Kevin Hart are among the anticipated guests.

We're told Brown's people told party organizers the singer will be showing up and that the invite came AFTER the events that went down at W.i.P. in NYC. In fact, the party tonight is being thrown by people connected to W.i.P.
