In an interview on a recent instalment of Nightline, Minaj described her father Omar Maraj as an abusive drug addict and alcoholic during her childhood.
Minaj explained: "I wanted to kill [my dad]. I used to wish he was dead... We were afraid for my mother's life because whenever he would have a real bad outburst he would threaten to kill her."
Omar Maraj tells TMZ that Nicki's story has been exaggerated, admitting to anger issues but denying that he was ever violent.
Sources close to the family say that Maraj is upset by his daughter's comments, as he was completely unaware that Minaj had felt this way.
Nicki Minaj is currently promoting her latest album Pink Friday: Roman Reloaded. She apologised for wearing a revealing costume during a recent performance on Good Morning America.
