Most boxing experts foresee Floyd Mayweather Jr would still keep his unbeaten boxing record of 0 loss and up his wins to 47 when Money May meets Argentinean boxer Marcos Maidana on Sept 14 for a rematch.

But the bigger fight that Mayweather may be knocked out is a new lawsuit from former girlfriend Shantel Jackson charging Mayweather of domestic violence, specifically pointing a gun at her and choking her. She filed the lawsuit on Thursday with the Superior Court in Los Angeles, California.

Mayweather was jailed in 2012 for two months for hitting former partner Josie Harris in front of their three kids. The boxer said the accusations by Harris were trumped up and Jackson then backed Mayweather and said Harris just made up the claims.

Now, Harris has the last laugh on Jackson as she tweeted, "well now well now ain't this some shit, the pot calling the kettle blac;; when I got my ass beat according to her I was a liar."

The Sydney Morning Herald reports that Mayweather had hit Jackson, 29, a former model and actress, many times and threatened her with a gun. She filed assault, battery, defamation, invasion of privacy, intentional infliction of emotional distress and harassment charges against Mayweather, 37.

Jackson claims the boxer first showed his violent streak in 2012 after he was released from jail for hitting a former girlfriend. In her lawsuit filed last week, Jackson alleged that her former fiancé twisted her arm and strangled her. In 2013, he bent her arm, restrained Jackson and pointed a gun at her foot and asked "Which toe do you want me to shoot?" The second incident was the offshoot of a couple argument when he ordered her to take off her 17-carat diamond engagement ring.

Jackson had filed a first lawsuit for invasion of privacy after Mayweather posted on social media sites images of her sonogram in which the boxer accused her of aborting their twin babies.

Mayweather actually has a history of hitting women because prior to Harris, he was also accused in 2001 by Melissa Brim, the mother of Mayweather's fourth child, of boxing her and hitting her with a car door. He repeated the physical violence after 5 months. Mayweather then filed a guilty plea, but Brim backed out of the lawsuit.

Jackson and Mayweather was a couple for seven years, but she split from him in 2013 after she could no longer stand the abuse and did not see the boxer changing.
