Farrah Abraham of 'Teen Mom,' Nicki Minaj argue on Twitter

LOS ANGELES, Jan. 11 (UPI) -- Farrah Abraham and Nicki Minaj didn't hold back in a Twitter argument Sunday.

The 24-year-old reality star and 33-year-old rapper traded insults on the social media site after Minaj called out Abraham for her treatment of her mom, Debra Danielson. Abraham and Danielson have had an often-contentious relationship, as seen on Teen Mom.

Minaj, who was catching up on the MTV reality series, started the spat by tweeting, "Farrah is a [expletive] to her mother." She followed up by chiding, "Your mother didn't open her legs and have that child. Be happy she's helping! Stop talking to her like that on tv u lil [expletive]."

Abraham shot back by tweeting, "Cause your a parent right? Your videos look like porn - Horrible good luck being negative #Godbless busy making TV." She later insisted, "To be clear my mom doesn't help me I help her. I love & care for my mom. Stop disgusting talk @NICKIMINAJ," and called the rapper a "rerun watching ignorant minion."

Abraham was 17 years old when she had daughter Sophia in February 2009. The father, Abraham's ex-boyfriend Derek Underwood, had died two months before, and she later battled Danielson for control over Sophia's care.

Teen Mom, now known as Teen Mom OG, airs Mondays at 10 p.m. ET. The latest episode saw Abraham ask Danielson to watch Sophia for a month as she filmed Celebrity Big Brother, while the next episode will see the pair talk about backlash on social media.
