Floyd Mayweather's ex-girlfriend, Shantel Jackson, used his credit cards on the sly and helped herself to his piles of cash ... according to the lawsuit he just filed against her.
According to docs, obtained by TMZ Sports, Shantel got access to Floyd's credit card accounts, and scooped cash around his house, to go on personal shopping sprees. He claims she shipped all her illicit booty to a secret location to keep him in the dark.
Floyd claims Shantel would praise him in public when he got bad press purely to gain his confidence.
