Things between Farrah Abraham and Nicki Minaj got ugly this weekend on Twitter.

'Teen Mom OG' Farrah Abraham Almost Did WHAT To Her Producer?!

After the rapper tuned into the latest episode of Teen Mom OG, she took to social media where she revealed her harsh feelings towards Abraham, and her treatment of her mother, Debra Danielson.

"Farrah is a c**t to her mother," Minaj wrote on Twitter on Sunday. Then, after a fan mentioned that Abraham's daughter, Sophia, had slapped her, Minaj added, "She was like bi**h go do some porn & leave gramma alone."

After seeing Minaj's tweets, Abraham fired back at the rapper, claiming her music videos looked like porn--and she would know. As fans will recall, Abraham starred in a series of sex tapes, one of which was titled Farrah Superstar: Backdoor Teen Mom.

Minaj then went on to suggest Abraham have more respect for her mother, who is helping her raise her daughter. However, Abraham felt differently, and claimed she was the one helping Danielson.

Unfazed by Abraham's comments, Minaj later let a re-tweet speak for her.

Teen Mom OG airs on Monday nights at 10 p.m. on MTV.
