According to a new $20 million lawsuit, Chris Brown raped a woman on a yacht parked at a Star Island home. The singer is being sued by a woman who claims Chris went from being friendly to raping her in a matter of minutes. According to the suit, Chris grabbed the phone of a friend she was FaceTiming and urged her to come to his house. The woman claims Chris motioned her toward the kitchen area on the yacht after asking if she wanted a drink. She claims that Chris gave her a red cup with a drink in the kitchen and they started talking. She claims she felt a sudden change in consciousness after he filled her cup a second time. According to the suit, the woman claims that she was drugged and fell in and out of sleep after Chris led her into a bedroom. The woman claims that Chris closed the bedroom door and started kissing her, even though she tried to leave. She said she mumbled for Chris to stop, but he persisted and raped her. Chris jumped up and announced he was done after ejaculating inside the woman. She claims Chris demanded she take Plan B after texting her. She claims the alleged rape is causing her severe emotional distress. The woman's attorneys say that she didn't report the alleged rape because she was embarrassed and she was a medical student. Mitchell and Vrabeck are committed to victims being heard and would urge anyone with information to contact them. We reached out to Chris, but no word back.
