Tmz reports that Floyd Mayweather proudly claims he had sex with Tiny. Mayweather was promoting his upcoming fight Friday against Marcos Maidana, when someone yelled, “What about T.I.?” — referring to the now famous Fat Burger fight. Listen closely, as Floyd says, “What about the bitch? I was f***ing his bitch.”As we previously reported … the photos Tiny posted of Floyd and his daughter on Instagram set T.I. off right before the melee … so he clearly suspected something was up. Floyd tried to talking to Tiny on the red carpet at the BET Awards … but she flatly denied him.
