TMZ broke the story ... Nicki and Samuels were arguing at a hotel pool in Dallas Monday night and took it upstairs to the room.
According to the police report, Nicki followed Samuels up to the room they were sharing, to make sure he didn't take any of her stuff. Nicki was in the room looking into her suitcase, which had some of Samuels' belongings, when she says he "grabbed the suitcase and as he was picking it up, he shoved the suitcase across [Nicki's] chin and lower lip."
The police report goes on: "[Nicki's] teeth struck the inside of her lower lip, causing the inside of the lower lip to cut and start to bleed."
