There's talk Nicki is going to bail on Birdman's Cash Money and follow Lil Wayne, so the fact that the mogul was sent walking seems like a big deal. He showed up at 1:45 AM and the club is supposed to close at 2, and you hear a guy at the door tell Birdman's posse the club was already closed.
At the same time, there was a good 15 minutes left and Birdman's kind of a big deal, and that may be why you hear someone say that Nicki didn't want him in.
Either way ... he didn't get in.
