While Floyd Mayweather Jr. (50-0, 27 KOs) may have generated revenue that nears the billion dollar mark in the course of his Hall of Fame career, he openly admits that he's not the best when it comes to keeping his financial records in order.

Mayweather has filed a lawsuit in Los Angeles County Superior Court, claiming that his former fiancée Shantel Jackson, who was known to boxing fans as Ms. Jackson, was robbing him blind by stealing “large sums of cash” during their relationship that spanned five years, from 2008 to 2013.

The lawsuit is a cross-complaint to Jackson's lawsuit that was filed in 2014, where she alleges assault, battery, invasion of privacy and defamation.

Their legal battle is due to get a trial date in the coming days. A court conference is scheduled for Monday, when a trial date is expected to be issued.

Mayweather claims Jackson gained his confidence during their relationship and learned intimate details about his spending habits, credit card accounts and where he kept “loosely” organized cash.

There is no information given as to the specific amounts that were stolen or any exact dates of when the thefts took place, but Mayweather is looking for triple the damages.

"As a result of that confidence, Mayweather, who's education ended at eighth grade, did not audit or otherwise inspect either his cash or his credit card statements for theft by Jackson," Mayweather's attorney wrote in the court documents.

Regarding Jackson's lawsuit, which was filed three years ago, she accused Mayweather of choking her during an argument, pointing a gun at her head, posting a sonogram photo on Facebook and publicly accusing her of aborting their twins.

“I have been embarrassed and humiliated more than I can ever imagine by Floyd,” Jackson said at a 2014 press conference with her lawyer Gloria Allred.

She said Mayweather twisted her arm and choked her during an argument in August 2012 and then pointed a gun at her in April 2013 while asking which toe she wanted him to shoot.

In his formal response this week to Jackson’s lawsuit, Mayweather attorney argues his ex-fiancée’s “own conduct, acts and omissions caused the injuries and damages alleged in the complaint.”
