*The husband of Lil Wayne’s baby mama Toya Carter, who appears with her in the BET reality show “Toya: A Family Affair,” was arrested at an Atlanta airport for allegedly trying to carry a fully-loaded gun onto an airplane.

Law enforcement tells TMZ, Mickey “Memphitz” Wright put his backpack through the X-ray scanner at Hartsfield-Jackson International Airport as he and Toya prepared to board a flight to Indiana. TSA agents quickly discovered the firearm and called the police.

According to authorities, Wright had a valid license to carry the weapon, insisting he had simply forgotten the gun was in his bag.  It’s still illegal, however, to bring it on a plane.

Wright was arrested and charged with carrying a weapon in an unauthorized location. He was detained in the Atlanta Airport Division of the Clayton County Sheriff’s office until bond.
