Floyd Mayweather Jr. revealed the reason why he broke up with Shantel Jackson: his ex-fiancée terminated the pregnancy of the twin babies the couple was expecting.

Mayweather posted a photo of Jackson's sonogram on his Facebook account to prove that his ex-fiancée had an abortion without his permission. The photo, which shows that the couple were expecting at least two babies, was later removed by Mayweather.

"The real reason me and Shantel Christine Jackson @missjackson broke up was because she got an abortion, and I'm totally against killing babies. She killed our twin babies," Mayweather posted on his Facebook account.

Mayweather will put his unblemished record on the line in a title unification about against Marcos Maidana on Saturday at the MGM Grand in Las Vegas.

Richard Schaefer, Golden Boy Promotions CEO, which is co-promoting the upcoming Mayweather vs. Maidana showdown, expressed concern about Mayweather's mental state.

Schaefer is worried that the reigning World Boxing Council welterweight champion may be letting personal issues affect his focus for his upcoming showdown with Maidana, wherein he is listed as an overwhelming 11-1 favorite.

"There's no question about it, he's distracted," Schaefer said via USA Today. "Think about it, we saw a very emotional Floyd. Clearly, with a day or two to go until fight night, against without question one of the most dangerous opponents he's fought, his focus should be 100 percent on the fight."

But on the flip side, Leonard Ellerbe, Mayweather Promotions CEO, is confident that the distraction caused by Mayweather's breakup and abortion issues will not affect the Grand Rapids native's performance on Saturday night.

Ellerbe pointed out that Mayweather has been preparing diligently for his showdown against Maidana, knowing that the reigning WBA welterweight champion has the ability to pull off an upset.

"I don't think Floyd Mayweather gets affected by too many things as it relates to preparation for a fight," Ellerbe said. "Come Saturday night, you will see an even more exciting Floyd. Maidana's a very tough guy, and we know he's gonna bring it. At the end of the day it's about wins and losses and Floyd's a winner."
