Nicki Minaj to Farrah Abraham -- You're a C, Bitch!!!

Nicki Minaj unleashed her fury on Farrah Abraham...after getting overheated from Teen Mom episodes.

Nicki tweeted "Farrah is a c*** to her mother. She was like bitch go do some porn & leave gramma alone."

Farrah fired back saying "Cause your parent right? Your videos look like porn. Horrible good luck being negative #Godbless busy making TV."

Nicki wasn't done ... "Your mother didn't open her legs and have the child. Be happy she's helping! Stop talking to her like that on tv u lil c***". In your case #BIGC***" Instead of dragging your mother, learn the difference between 'you're" & "your', ding bat."

Farrah ended the convo with this ... "You must really want attention--talk about women with respect - it's Sunday stop watching reruns & go to church. To be clear my mom doesn't help me i help her. I love & care for my mom. Stop disgusting talk @Nickiminaj."

Easiest story to write ... ever.
