Nicki Minaj hosted her album release party on Tuesday at a nightclub in NYC. She was supposed to make a big performance during the night with Flo Rida, but she turned up waaaay too late so she didn't even get in! "Nicki turned up to the club with about 25 people at 3:30 in the morning", an eyewitness tells. "She was denied entry at the door by the police because they said the venue was at capacity and there was nothing they could do to accommodate her". Ouch! Nicki wasn't very happy about it and left with her gang. Maybe you've learnt a lesson now?
