DaBaby Apologizes for Viciously Slapping Woman in the Face

3:48 PM PT -- The woman who DaBaby struck over the weekend has lawyered up, and it sounds like they're ready to have a chat with DB.

Attorney Matt Morgan tells TMZ ... "Morgan & Morgan has been retained to represent the interests of Tyronesha Laws. Ms. Laws has received DaBaby's Instagram message. We look forward to speaking with Mr. Kirk."

Yeah, you know it's serious when government names start getting thrown around. Luckily, DaBaby's already made it clear he's more than ready to talk.

12:09 PM PT -- DaBaby just issued a mea culpa to the woman he hit, implying he thought the gal was a dude ... and couldn't tell the difference because she was shining a light on his face at incredibly close range.

He goes on to acknowledge he was wrong in any case, noting that having flashing lights in your face is part of the biz and something he signed up for when he got in the game. That said, he offers an alternative to bopping him with a phone for next time ... zoom mode.

It also sounds like DB is trying to get ahead of possible coming repercussions for this, sending a message directly the woman, that he's willing to apologize and talk privately ... and make things right by whatever means necessary.

10:46 AM PT -- Law enforcement sources tell TMZ ... the victim in this case told cops that DaBaby got the wrong person when he smacked her, because she explained it was the woman next to her who had hit DaBaby first -- but received none of the retaliation.

We're also told when deputies arrived on the scene, DB had already left the venue. Our sources say the officers who responded did not notice visible injuries on the victim, and we're told she refused EMS attention when asked if she needed treatment.

Lastly ... our sources say this gal was given a form she can submit to the State Attorney's Office if she wants to press charges and pursue the case further. Unclear if she plans to do that or not though.
