Nicki Minaj had a wardrobe malfunction on her "Roman Reloaded" tour in Manchester on Monday night. 

While in a revealing black bustier, Minaj narrowly avoided a nip-slip on stage thanks to flowery nipple covers.

Minaj did not seem to notice the mishap, continuing to perform for her British fans which included Manchester City footballers Mario Balotelli and Gareth Barry.

Later in her set, however, the "Pound the Alarm" singer must have noticed the flowery covers were exposed, and addressed the crowd, saying "You guys have seen my boobs before. You won't tell anyone, will you?"

The night before in Nottingham, which was the first night of the UK leg of her tour, Minaj cautioned her fans that they could see more than they anticipated, according to the Daily Mail. 

“This is our first show so excuse any boobs popping out or any penises popping out!” she said.

But even with a potential nip-slip, Minaj seemed to have a great time, tweeting after her performance, “all i can say is there's no place like the uk =P.

"Just had the time of my life in Manchester. Cant [sic] begin to describe their energy... Unbelievable... #PinkFridayRELOADEDTour.”

Aside from suffering wardrobe malfunctions, Minaj has also been in the news due to her ongoing feud with Mariah Carey,  as they are both judges on hit talent show "American Idol" but cannot seem to get along. 

Earlier this month, even President Barack Obama weighed in on the situation, calling in to radio host Michael Yo’s “The Yo Show,” where he was asked if he could “repair the relationship” between the divas.

"I think that they are going to be able to sort it out, I am confident. I'm all about bringing people together, working for the same cause. I think both outstanding artists are going to be able to make sure that they're moving forward and not going backwards,” Obama said, according to NBC's "Today" show.
