Boxer Floyd Mayweather on Thursday reportedly revealed what he says is the real reason he broke up with ex-fiancee Shantel Jackson last year, taking to social media with a shocking claim.

“The real reason me and Shantel Christine Jackson @missjackson broke up was because she got a abortion, and I’m totally against killing babies,” he posted on both Facebook and Instagram, according to TMZ. “She killed our twin babies.”

The text was accompanied by an ultrasound image featuring two fetuses and their associated medical information.

It didn’t take long for Mayweather’s followers to react, with the majority slamming him for making such personal information so public. The posts were later removed and are not currently available on the boxer’s official social media accounts.

The boxer has said that he wants to settle down and have a baby, leading some to wonder whether the battle against Maidana will be his last.

In a separate message and photo that were also allegedly posted and then removed from Facebook Thursday, Mayweather took another apparent swipe at Jackson, writing, “Before all the plastic surgery I had to pay for. I’m an Indian giver I want my money back LOL,” the New York Daily News reported.

It is unclear if the ultrasound image is legitimate.
