Minaj was said to have told authorities her guest, who was not her boyfriend, had hit her in the lower lip during an argument, but refused to press charges.
Now, the star has hit back at the claims in a series of posts on her Twitter.com page.
She states, "The fact that u believe a man either slapped or punched me in the face + didn't leave on a stretcher...
"The media could pee on ur (your) leg + tell u (you) its (sic) raining. You'd believe it... stop it."
