Floyd Mayweather Jr ENGAGEMENT OFF Over Promiscuity?

Floyd “Money” Mayweather may have been engaged after reconciling with his fiance Shantel Jackson, but MediaTakeOut.com is reporting that Shantel called it off again a few months ago. And this time for good! Even after a $250 million dollar offer to stay!

Shantel’s reasoning is that she does not want to be in a marriage, unless Floyd is 100% faithful. Heck, she would prolly settle for 90% faithful . . . but Floyd offered NONE OF THAT. According to our snitch, Floyd wants to be allowed MULTIPLE SIDE CHICKS.

But that’s not the CRAZY part of it all. MediaTakeOut.com EXCLUSIVELY learned that before Shantel left, Floyd offered to MARRY HER LEGALLY – with NO PRE-NUP, if she agreed to his “side chick” terms. Floyd has a fortune worth about $500M . . . and without a pre-nup, Shantel would be entitled to as much as HALF OF IT.

Despite Floyd’s VERY GENEROUS OFFER . . . Shantel still said no.

But the love story between Floyd and Shantel is NOT over. MediaTakeOut.com learned that Shantel still LOVES THE CHAMP, and is willing to get back with him . . . and even marry him, if he cuts off all the SIDE CHICKS.

Shantel was photo’d last night, ALONE, at the Basketball Wives premiere party. And she looked AMAZING!!!
