Farrah Abraham: Nicki Minaj Corrupts Little Girls

Farrah Abraham has laid down the law with her daughter ... they now live in a Nicki Minaj-free zone.

Farrah tells us her 6-year-old daughter Sophia is no longer allowed to listen to or watch Nicki's videos because "they already have little girls asking for butt injections and wanting to color their hair crazy."

Farrah says Minaj took things too far when she insulted her publicly on Twitter -- calling her a c*** and a bitch -- and believes Nicki is being super disrespectful to single parents who are doing their best.

Farrah's parting shot at Nicki ... "She's dead to me ... that mess."

Actually there's one more jab... Farrah says Nicki needs to focus on her "rapist brother."
