The husband of Lil Wayne's baby mama #1 Toya Carter -- who co-stars alongside her in the BET reality show "Toya: A Family Affair" -- was arrested today at an airport in Atlanta ... after he allegedly tried to bring a gun onto an airplane.
Law enforcement tells TMZ, Mickey "Memphitz" Wright put his backpack through the X-ray scanner at Hartsfield-Jackson International Airport -- and TSA agents quickly discovered the firearm and called the cops.
According to police, Wright had a valid license to carry the weapon ... insisting he had simply forgotten the gun was in his bag -- but it's still illegal to bring it on a plane.
Wright was arrested on the spot and transferred to a nearby jail. He is still in custody.
