The 6-year-old, who has her own Twitter account, surprised fans by sharing a Snapchat video captioned, "@nickiminaj please stop saying bad words," on Monday.
"Hi everybody, Nicki Minaj is a total loser," Sophia says of the 33-year-old rapper in the clip.
Minaj had called Abraham a [expletive] on social media Sunday while watching back episodes of MTV series Teen Mom. The 24-year-old reality star responded to the criticism by saying the rapper's music videos "look like porn."
"I'm no longer allowing Sophia to watch Nicki Minaj videos," Abraham later told Us Weekly. "I've already had a constant battle with Sophia [over them]. It's inappropriate to imitate Nicki Minaj dance moves."
"Sophia wanted to meet Nicki Minaj to ask if her butt was real and how she can get a big butt," she added. "It's gotten out of control. I will not support her music or videos, not after Nicki Minaj has spoken negative and disgusting [words] about my daughter, my mother and myself."
Minaj objected to Abraham's treatment of her mom, Debra Danielsen, on the Jan. 4 episode of Teen Mom. The reality star, who has a contentious relationship with Danielsen, got in an argument with her mother after asking her to care for Sophia for a month.
Abraham came to fame on 16 & Pregnant, and welcomed Sophia at age 17 in February 2009. She went on to star on Teen Mom, which co-stars Maci Bookout, Amber Portwood and Catelynn Lowell, and airs Mondays at 10 p.m. ET.
