Nicki Minaj was denied entry to her own album release party Tuesday night, Radar Online reports.

The rapper was scheduled to host the release party for her new album, "Pink Friday: Roman Reloaded The Re-Up" at Greenhouse nightclub in New York City, but she was turned away at the door because the venue was at capacity.

An onlooker told Radar Online that Minaj came too late to get in. She had been scheduled to make an appearance at the event, which was sponsored by Smirnoff Iced Cake, with fellow rappers Flo Rida and Fabolous. 

“Nicki turned up to the club with about 25 people at 3:30 a.m.,” the witness said.

“She wanted to celebrate with her fans, but 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.”

“Nicki wasn't happy about it, so she and her group just left.”

"Pink Friday: Roman Reloaded The Re-Up" was released Nov. 19.

Minaj made headlines recently as a judge on the upcoming season of "American Idol."

Recently, she confessed that she won’t be watching the show when it premiers Jan. 16 because she’s concerned that she will appear too honest and harsh, like the show's infamous former judge Simon Cowell, according to the Daily Mail

“I'm scared. Maybe I shouldn't have been so like ... It's hard for me to not say how I really feel,” she said.

“Everyone else is so nice. I was just thinking back about some things and I was like, 'I wonder if that was not so nice.’”

“I don't think I'm going to be able to watch it. I'm going to be so nervous. But I know people are going to love it. I think it's a great dynamic.”
