This means war! Nicki Minaj and Farrah Abraham got into a huge Twitter fight on Sunday, January 10.

It appeared to have started when the "Superbass" songstress, 33, tweeted in some NSFW language that she, well, wasn't exactly a fan of the Teen Mom OG star, 24. (Presumably Minaj had watched Monday's premiere episode of the hit MTV show, which showed Abraham being rude to her mom and even being called out on it by her daughter.)

"Farrah is a c--t to her mother," Minaj wrote

After one of her followers joked about Abraham's 6-year-old daughter, Sophia, being angry at her mom for the way she treated her own mother, the rapper followed up with another tweet shortly after that read: "She was like b--ch go do some porn & leave gramma alone."

Abraham then tweeted back, "Cause your a parent right? Your videos look like porn Horrible good luck being negative #Godbless busy making TV."

But Minaj didn't stop there. The former American Idol judge then took another shot at Abraham.

"Your mother didn't open her legs and have that child," Minaj wrote. "Be happy she's helping! Stop talking to her like that on tv u lil c--t @F1abraham."

She followed it up by writing, "In your case #BIGC--T."

In response, the reality star took to both her Instagram and Twitter pages to fire back at Minaj.

"Some people should just shut up," Abraham captioned an Instagram snap of Minaj's tweets. "Like they see all the footage — like their parents — Like I care about their negativity #godbless busy making tv."

She also defended herself on Twitter, telling Minaj to stop watching Teen Mom OG reruns and go to church. Abraham even retweeted one of Minaj's tweets.

"To be clear my mom doesn't help me I help her," the Teen Mom OG star wrote. "I love & care for my mom. Stop disgusting talk @NICKIMINAJ."
