Recently, the Super Bass singer shared a photo of her butt in a thong, which she captioned "#ThongThursdays."

In June, the rapper surprised fans when she posted a topless photo of herself on Instagram. The American Idol judge left little to the imagination in the shot, which was snapped backstage in a state of undress, covering her breasts with her hands.

When Minaj's isn't posting sexy selfies, she's facing her critics. This week, Jersey City rapper Ransom accused Minaj of using ghostwriters. When TMZ caught up with the Queen of the Barbz in Los Angeles, she snapped: “I rap better than him.”

“I’m not even a man and ni--as got my d-ck in they mouth,” said Nicki, who was rocking a blonde wig and a snug Alexander McQueen dress. “I slaughter these ni—as. Period.”

The Pink Friday rapper continued to rant, slamming Ransom.

“I’m undisputed because I’m the only female rapper that [from] day one, I don’t need no mother-----n’ ghostwriter,” she added. “So if you telling that lie, you must be real f---in’ desperate and you still ain’t gon’ pop. How ‘bout that?"
