There were so many people in the street that she couldn't get into the venue, so she left the area as fans chased her limo down the street! Nicki showed up 30 minutes later and caused chaos by walking down the street!

Earlier that day, Nicki Minaj dismissed Internet rumors saying she is pregnant with her second child.

While answering questions on Instagram Live ahead of the concert, a fan asked, "Are you pregnant?"

Nicki replied:

"Am I pregnant? Oh, I did mean to tweet this: I'm not fat, y'all, I'm pregnant. Oh wait. Did I say it wrong? I'm sorry. I think I said it wrong. I meant to say I'm not pregnant, I'm fat. But thanks, guys, for all the congratulatory messages."
