Nicki Minaj went off on Kevin Federline for dissing Britney  

The Barbz, good news your girl Nicki Minaj is Team Britney all the way. 

And she proved it during an episode of her "Queen Radio" podcast, by going off . . . HARD . . . on Kevin Federline for making their business public.

She said, quote, "Do you understand what kind of a clown you have to be to be a whole, grown XXXXXXX man, and as soon as you see somebody happy and getting married and moving on and being free and feeling good in their own skin, to do the very thing that you know is going to attempt to break them down?" She also called him a COWARD for running to the media, and trashed him for bringing the kids into it. 

And, in closing, she told Kevin to leave Britney the XXXX alone.
