My Sexual Assault Accuser Was A Whore ...The Game Reveals To Judge

The Game's asking the judge in his sexual assault case to make his accuser's sexual history fair game ... history that allegedly includes prostitution.

The rapper's legal team is opposing Priscilla Rainey's request to prohibit them from raising issues about her alleged past in the trial, which she claims is only meant to inflame the jury and victim shame.

But Game's team just filed legal docs claiming her history is a direct reflection of her credibility ... specifically allegations she was a prostitute and engaged in a "promiscuous" lifestyle. He also wants the jury to know she allegedly spent time in a mental institution.

Game also wants the jury to know she's allegedly been arrested for theft.

TMZ broke the story ... Rainey sued Game for $10 million accusing him of sexually assaulting her while she was a contestant on his reality show, "She's Got Game." She claims he put his hand up her skirt and rubbed her vagina and buttocks.tmz
