Floyd Mayweather and his fiance Shantel Jackson have broken up. 

Shantel, who goes by the name Miss Jackson aired Mayweather out on Twitter after a fan asked her why she didn't attend a recent Los Angeles Lakers game with Mayweather. 

Last week when the Lakers played the Boston Celtics at the Staples Center, the boxing champ was pictured seating courtside with Atlanta designer, Delicia Cordon and her friends. See photos here:

"Why aren't you court side with money?" the fan asked, to which Miss Jackson responded, "Cause he's busy with sit fillers."

She also added, "Funny when a person tries to top you."

Back in December, Mayweather talked about Miss Jackson and seemed to be in love with her. 

"Miss Jackson is my fiancée. I stand behind her 100 percent. No relationship is perfect. Sometimes we don't see eye to eye, [but] I love Miss Jackson and she loves me. Any woman that's attractive that's around me doesn't mean that she's my girlfriend or she's my lady or I'm sleeping with this woman. I'm happy with one woman," he told Sister 2 Sister magazine. 

Back in December, Mayweather showed off diamonds on his Instagram page he bought for Jackson during Christmas.

"Ring... 25 CARAT fancy intense yellow. Bracelet... 50 CARAT fancy yellow," Mayweather captioned the photo.

In the second image, Jackson flaunts another diamond ring and bracelet with charms.

"I showed her right hand and forgot to show her left hand. Sorry ladies & gentlemen. #TMT themoneyteam.com," he wrote.
