American boxer and five-division world champion Floyd Mayweather, Jr. is defending his right to call out his ex-fiancée’s abortion on social media.

Shantel Jackson, who aborted her and Mayweather’s twin children, is suing Mayweather for defamation, assault, and invasion of privacy but the 37-year-old boxer is working to get her lawsuit dismissed.

Mayweather said that Jackson asked him to help her “become famous” and used his celebrity to build her up. He added that since they both are famous, the public is interested in every aspect of their relationship including the breakup.

“At age 37 I am an undefeated boxer. I have been the world champion in five different weight divisions,” the boxer claimed in a sworn statement. “After we broke up, there was a lot of media talk about why we broke up. I expressed myself on the breakup and abortion … and posted it on social media.”

“Both parties are public figures,” he said in a legal document. “Abortion is a public issue. A public figure involved with another public figure in a public relationship can expect publicity, not privacy, about why it ends.”

This is Mayweather’s defense for calling Jackson out in a series of social media posts including a sonogram picture on Instagram last Spring that read, “The real reason me and Shantel Christine Jackson @missjackson broke up was because she got a abortion, and I’m totally against killing babies. She killed our twin babies.”

The post has since been deleted.

Mayweather has seen his share of legal issues. In 2002 he was charged with two counts of domestic violence and one count of misdemeanor battery. Then in 2004 Mayweather was given a one-year suspended jail sentence after being convicted of two counts of misdemeanor battery against two women. In 2010 his former girlfriend, Josie Harris, filed a domestic battery report against him and he was taken into custody on September 10 but was released after posting a $3,000 bail. In December, 2011 a judge sentenced Mayweather to serve 90 days in the county jail, 100 hours of community service, a 12-month domestic violence program, and a fine of $2,500.

A judge has yet to rule on the recent legal issue regarding Shantel Jackson.
