Derrick Rose has been hit with some serious accusations. A woman who claims to be his ex-girlfriend accused the NBA superstar of drugging and gang raping her with two of his friends in 2013.

In the lawsuit, the woman is identified as "Jane Doe," according to TMZ. She says she and Rose dated from 2011 until 2013. The sexual assault allegedly took place in August 2013. According to the plaintiff, Rose along with his personal manager Randall Hampton and pal Ryan Allen slipped drugs into her drink with the aim of raping her.

She managed to escape and return home with the help of a friend, but later that night Rose and his friends broke into her apartment and gang raped her while she was incapacitated. She says she only comes forward with the accusations now because she was "ashamed and embarrassed" of what happened and concerned her "conservative family" would find out.

The woman additionally claims that during her courtship with Rose, he tried to sleep with her friends, pressured her to masturbate in front of him and to take part in group sex with strangers, which she refused to do.

Rose has not responded to the allegations.
