NICKI MINAJ CLAIMS HER BOYFRIEND BEAT HER . . . AND YOU WON'T BELIEVE WHY!!!

imyourmedia.com just received some DISTURBING news about an incident between Nicki Minaj and her boyfriend SAFAREE.

According to a member of Nicki's ENTOURAGE the two got into a PHYSICAL FIGHT . . . and that during the fight Nicki got HIT IN THE MOUTH. And the fight started because Nicki suspected her BF was texting AMBER ROSE!!!

It all began when Nicki, Safaree and their entourage were staying at the Palomar Hotel in Dallas two nights ago. The group was downstairs at the hotel pool, when all HECK BROKE LOOSE.

The insider, who was NOT there to witness the incident - but has FIRSTHAND knowledge, tells MediaTakeOut.com, "Nicki is EXTREMELY jealous of Amber. Rose She thinks that she and [Safarree] were [having relations]." The insider continued, "Nicki took [Safaree]'s phone to see who he was texting. She always does that and he [usually] doesn't care. But this time he [protested] and they started arguing."

The arguing got louder, and the couple started making a scene. The insider continued, "It was very embarrassing, Nicki was all in his face and they were both yelling. It was very hood."

And that's when, the story gets MURKY.

Nicki and Safaree continued arguing, and returned to their HOTEL ROOM. While inside the two began to PHYSICALLY FIGHT - and according to our insider, NICKI and Safaree are telling people close to them that PUNCHES WERE THROWN.

Who threw WHAT punch is still not clear. The insider tells us that Safaree claims that it was NICKI who attacked HIM . . . and that he was trying to RESTRAIN her. But Nicki told people that Safaree PUNCHED HER IN THE FACE.

In either event, police WERE CALLED to the room. When they arrived Safaree was NOT THERE to be questioned. Police questioned Nicki - and checked her for ANY INJURIES (which they found none). The officers then filed an INCIDENT REPORT - and DECLINED to issue an ARREST warrant for Safaree.

Nicki and Safaree are STILL TOGETHER. And Safaree operated as her HYPE MAN at last night's concert. Even though TMZ is reporting virtually the SAME THING as we are, Nicki is DENYING IT. She came out publicly - denying that ANYTHING happened that day.
