2:26 PM PT -- Grace Jabbari's cross-examination continued this afternoon, and attorney Priya Chaudhry continued to question Jabbari's alcohol consumption -- including during the day/night in question. Chaudhry also asked why some injuries didn't appear as prominent when she finally got with cops ... and Jabbari said she'd cleaned herself up a bit after arriving at his place that night.

One highlight during cross ... Chaudhry attempted to ask Jabbari about the suicide of an ex-boyfriend of hers, and that made Jabbari burst into tears and require a break. Chaudhry went on to ask her questions about her visa status ... and also asked if she'd seen the security videos/photos of her partying that night -- to which Jabbari accused Chaudhry of "posting."

It appears today's court session is wrapping, and Jabbari's cross should continue tomorrow.

10:50 AM PT -- Grace Jabbari's cross-examination got underway this afternoon -- and right out the gate, Jonathan Majors' defense attorney Priya Chaudhry tried to paint the alleged victim as someone who was constantly feuding with her ex, and who had problems with alcohol to boot.

Chaudhry is reported to have asked a series of questions about her knowledge of Majors' background -- professional or otherwise -- and whether she once had a photo album of Majors' pics ... although it's unclear how Jabbari responded to these. Chaudhry also apparently spent a fair amount of time asking Jabbari about her trial prep with prosecutors, and whether she'd been instructed on pre-determined answers ... which Jabbari denied.

Chaudhry is also reported to have asked quite a bit about Jabbari's past drinking habits -- including whether she was downing a lot of booze during the night in question ... not to mention other times Jabbari might've resorted to alcohol throughout her relationship with JM.

Chaudhry appears to have gotten Jabbari to acknowledge she would, at times, resort to drinking during arguments with Majors. She hasn't gotten to the night in question yet, but Chaudhry is working her way there. They're on a lunch break now, and her cross-examination will continue later this afternoon.

Jonathan Majors' assault trial is heading into its third day and his accuser, Grace Jabbari, will be back on the stand -- but this time his attorney will have a chance to grill her about the alleged attack.

The actor's ex-girlfriend -- who is the prosecution's star witness in the case -- is all set for cross-examination from the defense Wednesday ... this after testifying Tuesday about her POV of the incident that's landed them in court.

Most notably, Jabbari backed prosecutors' assertion she was victimized that fateful night in March -- when Majors was arrested and ultimately charged with assault and harassment.

Early Wednesday, she testified she'd taken 2 over-the-counter sleeping tablets on the evening of the alleged assault. She says that's why she ended up asleep, and half-naked on the bathroom floor at Jonathan's apartment -- and when she woke up, police were standing over her and she could hear Jonathan in the adjacent room.

He's pled not guilty, and this entire time ... he and his attorneys have insisted he was the one who was attacked that night -- not the other way around. Prosecutors, however, told a different story in their opening statement ... insisting Jabbari had been in an abusive relationship with the guy, which boiled over in brutality in a private car they were in.

Jabbari reiterated that while on the stand, telling her side of the story by explaining she caught JM texting another woman and confronted him about it -- snatching his phone away, and then claiming he roughed her up in an attempt to get it back. She also testified that when she tried to flee the car, he grabbed her and threw her inside again ... something that was reportedly depicted in surveillance video that the prosecution played for jurors in court.

After their squabble ... Jabbari says she went to a party with strangers she'd just met in an attempt to take her mind off things -- and while she's appeared uninjured in photos and videos showing her at the club, GB testified she was actually hurt and licking her wounds.

There were other bombshell moments during her 1st day on the stand, including a recording she'd once taken of Majors during an argument -- in which he apparently called upon her to be more like Coretta Scott King and Michelle Obama, while shouting "I'm a great man!"

Jabbari also claimed Majors had been aggressive with her in the past, including one alleged time when she says he lost it on her after she brought up her ex-boyfriend's doggo.

Majors remained stone-faced during Jabbari's testimony, which will now pivot to her being questioned by his defense attorneys -- who will undoubtedly try to pick apart her story.

At some point, prosecutors will presumably call other witnesses -- including the driver of their private car that night ... who would be the only material, and presumably unbiased, witness to Majors and Jabbari's conflict.
