During a Grammys afterparty Sunday, Janelle Monáe called out Nelly for performing at Donald Trump's inaugural ball, calling him a 'fool.'

Now, they are being taken to task by their peers in the music industry, with Janelle Monáe specifically calling out Nelly in a post-Grammys freestyle. When she was given the beat to Nelly’s 2002 hit “Hot In Herre” to rap over, she obliged, but used the opportunity to criticize the St. Louis native for selling out.
