NBA YoungBoy is getting all the love during his 'MASA (Make America Slime Again)' tour, especially from his co-parents. Aside from his wife, Jazyln Mychelle, making a rare pop-out at his opening show, Yaya Mayweather has shared multiple messages praising her son KJ's father for his talents. Her latest brag was about the rapper singing a song he allegedly wrote about her.
