Floyd Mayweather dumps Shantel Jackson, infamous boxer repo'd ex-fiancee's Bentley after cheating scandal? Beauty 'chills' on Instagram [PHOTOS]

Rumors suggest that Floyd Mayweather's engagement to Shantel Jackson is officially off - apparently, the undefeated boxer's nonstop flirting ruined the relationship. And now, Mayweather wants nothing to do with his former flame.

UPDATE: Floyd Mayweather's ex-fiancee Shantel Jackson 'broke' - former girlfriend 'pawns' expensive Birkin bag, luxury car repo'd by legendary boxer?

According to the infamous gossip webloid MediaTakeOut.com, Mayweather actually had Jackson's car repo'd! The 2013 Bentley Continental was a gift to Jackson - but the luxury car still belonged in Mayweather's name after the break-up. So, he took it back!

MTO reports that Jackson's been spotted driving around LA in the "borrowed" vehicle - until now.

Apparently, a member of Mayweather's posse found the car parked outside on the street over the weekend. So the guy went and got a spare key, then had the flashy Bentley repo'd! It was allegedly sold back to the original car dealership.

Check out a photo of the car (now back on the market) here.

Do Mstars fans think Mayweather would really do such a thing?

Meanwhile, Miss Jackson seems to be handling the major diss just fine, spending ample time with her girlfriends:

missjackson: "Girls night out..."

missjackson: "Flawless."  

missjackson: "About that night..."
