Nicki Minaj has hit back at her ex-boyfriend Safaree Samuels.
The 'Superbass' hitmaker has branded the 34-year-old rapper too dumb to write her raps after he alleged he was a ghostwriter for some songs on her album 'The Pinkprint'.
In a video obtained by gossip website TMZ, she said: "'Till this day I never stopped. See a bitch ass n**** can't write my raps. You know why? You don't have the heart or the mindframe or the motherf***ing intellect bitch n****. You don't even know how to pronounce these motherf***ing words in my motherf***ing rap bitch."
In his track 'Lifeline', Safaree also dissed Nicki's new boyfriend Meek Mill.
He rapped: "This n**** bent outta shape with a gorilla face, my bars on 'The Pinkprint' no one will ever match, my d**k print, little n*****, you can never match ...
"When you was pulling up, I was pulling out, I know real s**t I ain't gonna talk about, I seen the text messages, I seen the emails, somebody tell me why he's talking like a female."
The track also hints at Safaree's sadness that the relationship ended after over a decade.
He raps: "What a shame, it took a split for them to know I was your man, got so tired of hidin' it, head high with no pride in it, guess I wasn't cool enough cause in our pictures we hidin' it.
"Twelve years up in flames, thought you woulda had my kid, year three got engaged, now we movin' out of rage."
