Young Thug Sends Loving Message to GF Mariah The Scientist Amid Potential YSL Mistrial

Young Thug sent a heartfelt message to his girlfriend Mariah The Scientist in court today -- as proceedings were dismissed for the day, reigniting those mistrial convos once again!!!

TMZ Hip Hop obtained a photo of Thugga in court wearing a shirt that read “I ❤️ Mariah” as the presiding judge cleared the courtroom to consult with him.

It's not the first time his fashion choices have sent out a bold message ... we've still yet to see any more movement from "Sex Records" after he introduced the term.

Mariah has been heavily supportive the entire trial … she recently traveled for miles to the Fulton County jail for a bittersweet 3rd anniversary ... only to be turned away over a technology fail.

The jail blamed a temporary outage caused by their video visitation system to prevent visitors that particular afternoon.

Trial was dismissed until Monday morning, where it's being said a decision for the defense's mistrial proposal -- and any potential plea deals -- will be made. Defendant SlimeLife Shawty was introduced to info about another incarcerated defendant and the prosecution is demanding the case be dismissed.
