Nicki Minaj 911 -- 'Look at What He Did to My Face'

Dallas police have released the 911 tape from the Nicki Minaj hotel fight last month -- in which you can hear a woman, referred to as "Nicki," scream ... "Look at what he did to my face!"

As TMZ first reported, cops responded to the Palomar Hotel on July 12th -- after Nicki complained that some guy she knew hit her in the face with a suitcase.
