The Game turned Lil Wayne's 30th birthday bash into an impromptu fight club when he got into a brawl with another rapper and had to be kicked out of the party ... and TMZ obtained the video.
Sources at the party tell TMZ ... Game was in Hollywood Thursday night with Chris Brown, Sean Kingston and the b-day boy himself. We're told Game was allegedly minding his own business when rapper 211 approached and, according to our sources, started talking smack.
We're told things escalated and the smack-talking turned into an all out fight ... which ended with Game allegedly punching 211.
TMZ obtained video just seconds after the fists stopped flying and you can see the two rappers still going at it as security guards rush in to break them up. We're told after security got a hold of the situation, Game was kicked out of the section.
Sources tell us the rappers have had a beef for awhile and that's what led to the altercation in the first place.
Calls to both rappers were not returned.
