The woman who accused Straight Outta Compton star Jason Mitchell of physically assaulting her, forcing her to seek medical care, is speaking out and is threatening to sue.

Emily Marquez, 18, told TMZ she believes the actor slammed her to the ground because she rejected his passes in front of his friends. She also explains in the video that things only got physical when he tried kissing her neck.

"Right when he [had] seen me, he was all up on me like, 'Damn, ma,'" she said. "I wasn't feeling it. I was like, 'I don't even know you.'... We were playing a game and he started kissing on my neck. I was sitting like this, and he was behind me and I kind of pushed his head up and I was like, 'Get away.'"

Take a look at what else she has to say, below:

Marquez claims the actor assaulted her at the Ritz Carlton hotel, grabbing her arms and throwing her to the ground by her hair. She says he fled the scene after calling her a b***h.

Mitchell's reps say, contrary to what's being reporter, Marquez threw the first physical jab after trying to crash his party in his hotel room.
