Rappers knooow better than to flex on Nicki Minaj. But just in case they need a reminder, the Queen Barbz flexes her lyrical muscles on the catchy remix to Rae Sremmurd's banger 'No Flex Zone.'

Over Mike WiLL Made It's sinister beat, Minaj reminds us why she's a trendsetter and a go-getter.

"Running this game for five years / Guess that's why my feet hurt / Wonder when they bite me / Do these bitches teeth hurt / Yes, I'm an icon / That's me on your T-Shirt / Thought you knew better / Do your research," she raps.

At the end of the song, Minaj also warns the thirsty fellas stalking her Instagram page, "If you're ugly it's a no text zone / It's a no sex zone / It's a no flex zone."

Besides releasing a new song, she posted Instagram videos of a plaque she received for selling over three million copies of her debut album, 'Pink Friday.'

In addition to the 'No Flex Zone' remix, Minaj can also be heard on Cam'ron's new version of his 2012 song, 'So Bad.'

Nicki Minaj is straight flexing on all of us right now.
