Swae Lee's girlfriend has allegedly been arrested for headbutting the popular crooner during a heated exchange.

Law enforcement sources told TMZ that the Rae Sremmurd rapper and his ex, Marliesia Ortiz, had an argument at Swae's home outside L.A. in early August, when she allegedly began throwing objects at him.

Security tried to remove her from his home, but not before she headbutted her famous boyfriend, now ex-boyfriend.

According to TMZ - Marliesia actually called the cops on Swae and alleged that he had sexually assaulted her, but when cops arrived, she changed her story. 

She eventually admitted to starting the altercation by breaking items in his house and hitting him but claimed the rapper also strangled her. Neither of them had any visible marks when the cops arrived, but they arrested her anyway.

The breaking news outlet is also reporting that the L.A. City Attorney is considering charging her with misdemeanor assault.
