We just learned of a SHOCKING piece of information. According to a VERY WELL KNOWN and reliable music industry insider, rapper Nicki Minaj and R&B singer Keyshia Cole got into a PHYSICAL FIGHT three weeks ago inside of a Los Angeles recording studio.

According to MediaTakeOut.com's snitch, the two were supposed to be recording a song together when some words were exchanged - between Keyshia and one of the guys with Nicki.

The insider explained, "Someone said something out of line to Keyshia, and she wasn't going to stand for that. Then Nicki got involved and it was MAYHEM."

MediaTakeOut.com's snitch continued, "Keyshia was ready to fight and there was a lot of people in each others faces and pushing, but no punches were actually exchanged."
