Mike Epps -- Not Charged But Lectured For Allegedly Punching A Woman

Mike Epps will not face criminal charges for allegedly punching a woman in the face at a movie premiere party ... but he's not completely off the hook -- and neither is the alleged victim.

We broke the story ... Simone Shepherd says she got into it with Epps' wife at the "Haunted House 2" premiere party ...and claims Epps hauled off and smacked her in the face.

Mike insists he never laid a finger on her ... but Shepherd showed us photos of her swollen jaw and claims the injuries were courtesy of Epps.

Law enforcement sources tell TMZ ... Epps won't be charged, but he's been ordered to attend a City Attorney hearing -- where he'll be lectured on the law and the importance of keeping the peace.
