Rapper Nicki Minaj has hit back at her former lover Safaree Samuels, branding him too dumb to write her raps.

The "Anaconda" hitmaker reacted so as it was alleged that the 34-year-old rapper was a ghostwriter for some songs on her album "The Pinkprint", reports femalefirst.co.uk.

In a video obtained by tmz.com, 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 Minaj's new love Meek Mill. The track also hints at Safaree's sadness that his relationship with Minaj ended after over a decade.
