Lady Gaga isn't the only one showing some serious skin today.

While Nicki Minaj didn't quite match the bizarre singer's extreme level of nudity, she did go topless on her Instagram last night -- posting a very risque photo showing her ample cleavage, barely covered by her hair.

The rapper and former "American Idol" is no stranger to showing off her ridiculous curves, but this is definitely one of the more revealing shots of her in a while.

Check out the gallery above to see more of sexiest looks -- she clearly loves her cleavage!
