Taking to the stage at Manchester's MEN Arena on Monday night, the Super Bass hitmaker flashed a little more flesh than she bargained for as she appeared in a skimpy black bustier.
Performing a series of energetic dance moves, the rapper didn't seem to notice as her flower-shaped nipple covers popped out for all to see.
The previous evening at Nottingham's Capital FM Arena, Nicki warned audience members that she and her dancers could be exposing a little more than anticipated throughout the show.
She said: 'This is our first show so excuse any boobs popping out or any penises popping out!'
Despite the wardrobe malfunction, the R&B star seemed delighted with her performance and was full of praise for her British fans.
