It's not exactly a secret that Floyd Mayweather and Shantel Jackson went through a really bad breakup. For proof of that, all you need to do is take a look at this photo that Mayweather posted on Instagram a few weeks ago. But now, it looks like Mayweather is intent on making his breakup with Miss Jackson the worst one ever.

A short time ago, Mayweather took to his Facebook account to explain why he decided to break things off with his ex-girlfriend. He has since deleted the post that he put up. But the revelation he made in it was, well, stunning to say the least:

WTF?!?!? There's TMI—and then there's the info that Mayweather just shared. And as you might expect, Twitter is outraged right now with regards to what he decided to post on Facebook:

This may just go down as the worst social media fail in the history of social media.

UPDATE:

Mayweather has responded. He didn't apologize for putting up the post on Facebook, though. Instead, he shared a #TBT photo on Instagram a short time ago, which he then deleted:

His caption read: "#tbt @missjackson Before all the plastic surgery I had to pay for. I'm a Indian giver I want my money back LOL #ShantelJackson #FloydMayweather #TheMoneyTeam #PlasticSurgery #TMT."

Is Mayweather bent out of shape because Miss Jackson is reportedly running around with Nelly now or...?

Regardless, this situation seems like it's only going to get worse from here.
