Floyd Mayweather took to Instagram and Facebook to tell fans the real reason he broke off his engagement to Shantel Jackson. The picture was a sonogram of their alleged twins captioned she had an abortion.

"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. #ShantelJackson #FloydMayweather #TheMoneyTeam #TMT" 

The couple dated for four years and the boxer proposed in 2013 with a $10 million ring. He removed the posts after receiving tons of negative comments from users.

"You always want a strong, beautiful woman that you can share everything with. But I have to go my separate way," he told MLive in April of the split.

"She's focusing on her career in L.A., which is acting. And I'm focusing on my career, which is boxing. Sometimes people can outgrow one another, but we're still friends."

Jackson recently told TMZ she has moved on, and is rumored to be dating rapper Nelly. The pair was spotted together Monday at a Miami Heat game. Nelly also posted a photo of her for "Woman Crush Wednesday" on Instagram, but has since taken it down.

Mayweather, who has signed a $200 million deal, could not help but throw more shade at his ex. After she uploaded a picture with her new man, he added another old picture of her, this time claiming he paid for plastic surgery.

The caption reads, "#tbt @missjackson Before all the plastic surgery I had to pay for. I'm a (sic) Indian giver I want my money back LOL #ShantelJackson #FloydMayweather #TheMoneyTeam #PlasticSurgery #TMT."
