Nicki Minaj had a wardrobe malfunction Monday night on her "Pink Friday: Roman Reloaded" tour in Manchester, England.

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

Minaj, who did not initially seem to notice the mishap, continued to perform for her British fans, including Manchester City footballers Mario Balotelli and Gareth Barry.

Later in her set, however, the "Pound the Alarm" singer seemed aware she had become exposed, asking the crowd, "You guys have seen my boobs before. You won't tell anyone, will you?"

The previous night, in Nottingham, which was the first night of the U.K. leg of her tour, Minaj cautioned 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.

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.”

Minaj has also been in the news recently over an ongoing feud with Mariah Carey, a fellow judge on the hit Fox TV talent show "American Idol."

Earlier this month, President Barack Obama, on a call-in to Miami radio host Michael Yo’s, “The Yo! Show,” was asked if the president could help “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,” said Obama.
