Kevin Hart -- THOT Repellant ... Wears Fiancee's Name at Strip Club

Kevin Hart dispensed with the formality of introducing his fiancee to his ex-wife at the strip club Monday night ... because he had her name plastered on his body.

We got photos of Kevin at Magic City strip club in ATL ... where he and fiancee Eniko Parrish dropped $40K to celebrate their engagement. But check out Kevin's shirt ... with Eniko's name emblazoned on it.

As we reported ... Kev's ex, Torrei, was partying in the club that night with her "Atlanta Exes" co-stars ... and while she and Kevin never spoke, we're pretty sure she got his message.
