Nicki Minaj and her boyfriend Safaree left SupperClub in Hollywood on Tuesday night, and the R&B superstar quickly went from striking a sexy pose to mouthing off when one man asked about rumors that she uses ghost writers.

Minaj fired back, "I'm not even a man and n****s got my d**k in their mouth," adding, "Are you f*cking serious? I'm undisputed because I'm the only female rapper ... I don't need no motherf*ckin' ghost writers!"

So how exactly did the rumors start? Apparently the rapper Ransom, who has worked with Nicki in the past, recently released a song called "Man Alone" where he sings, "Before Nicki was wearing those crazy wigs, I was doing verses for her, just hoping she made it big." Yikes! Was he actually suggesting that he wrote her tunes?

Maybe not. After the song came out, Ransom tweeted, "As far as I know she writes her own [songs]." So, was he just trying to generate more buzz for himself? If so, we think Nicki has every right to be angry with him!
