After four years of being together, Jennifer Lopez and Alex Rodriguez have split.

While it came as a shock to many, several sources told news outlets that it was actually a long time coming.

An insider revealed to Us Weekly that the last time they have seen each other was Mar. 1, and there have already been issues in their relationship.

The 51-year-old singer and 45-year-old athlete first met in 2005 and started dating 12 years later. They were even supposed to get married, with Jennifer Lopez and Alex Rodriguez's wedding ceremony postponed twice because of the COVID-19 pandemic.

However, the main reason for their breakup may have been the cause of another woman, as per Page Six.

Their source claimed, "The Madison LeCroy scandal was the reason they finally broke up."

"There were already problems, but Jennifer was really embarrassed by it."

Early this year, rumors swirled of a romance between A-Rod and "Southern Charm" star Madison LeCroy.

At the time, however, multiple sources found that there was no connection between the two.

"I know that there was, like, an NDA signed, which doesn't seem to mean anything anymore, not worth the price of the paper they're printed on."

Rose added, "DMing baseball stars and stuff, and it's all good. It's not anybody's fault, but it's turned into something a little more cheesy than I would've liked, but that was bound to happen."
