Keyshia Cole, Birdman Lawsuit: Sabrina Mercadel Suing Over Beating And 'Prostitute' Slander

Singer Keyshia Cole is getting slapped with a lawsuit from her victim, Sabrina Mercadel after her scuffle over YMCMB CEO, Birdman.

Mercadel's lawyer -from the Johnny Cochran firm- states in the lawsuit that the "I Should've Cheated" singer mistaken Birdman's guest as a prostitute telling Sabrina, "You can get your money later," then slapping her butt.

The victim's lawyer says that she was never romantically involved with the rapper and only had a "plutonic relationship."

Sabrina's LAWYER repeatedly protests that his client was NOT in a romantic relationship with Birdman ... the attorney calls the RELATIONSHIP "plutonic."

In October, Mercadel was granted a restraining order after filing court documents claiming that she was slashed with fingernails and may have suffered long term injuries stating that he finger was badly damaged. The singer must remain 100 yards away from Mercadel and may never contact her.

In September, Keyshia was arrested in Los Angeles after attacking Mercadel for allegedly messing with her rumored boyfriend, Birdman.

The former cash money employee denied having a relationship with the rap mogul and stated that she's known him since she was young and has worked for him for over a decade.

TMZ reported, the singer arrived at the YMCMB's president's L.A. condo around 5 am where 4 other women were present including the victim. Sources told the site that Sabrina walked out of the rest room when Keyshia attacked her while yelling, "What are you doing with my man?!"

According to TMZ, Sabrina broke her silence and says that she was never involved with the rapper and has worked with him for over a decade. Sabrina did get treated at the ER and now is reportedly on pain medication.
