Johnny Depp searched Amber Heard for cocaine once -- an inspection that apparently went in and around her body, including private areas ... at least according to a forensic psychologist, who claims Amber made the allegations during her evaluation of the actress.
Dr. Dawn Hughes was Amber's witness who took the stand Tuesday to combat what Dr. Curry -- JD's witness -- alleged about her last week ... namely, that Amber suffered from a couple different personality disorders and that she was making up symptoms of PTSD.
Hughes testified to the exact opposite ... telling the jury her evaluation of Amber -- which consisted of about 29 hours total -- made her believe she was, in fact, a victim of domestic abuse.
There were some disturbing things Dr. Hughes claims Amber told her ... including allegations of Johnny kicking her in the back, pushing her, slapping her and alleged instances of sexual violence, much of which she says occurred when JD was under the influence.
One other bombshell claim from Dr. Hughes, based on what she says Amber told her ... Johnny, at one point, allegedly subjected Amber to a "cavity search," poking around on the inside of her vagina to see if he could find cocaine he believed she was hiding from him.
Another disturbing alleged tale ... Dr. Hughes claims Amber told her that Johnny penetrated her with a bottle once, and that the whole time she was worried it might be broken and cut her up inside.
She relayed even more of Amber's claims ... including that Johnny was incredibly jealous, allegedly contacting male costars of hers to say he had eyes on the set ... which Hughes says made Amber incredibly anxious that he'd show up on set at any given moment.
James Franco and Billy Bob Thornton were name-dropped as some of the guys Johnny was supposedly angry about ... anger he allegedly took out on her in the privacy of their home.
