Jennifer Lopez is reportedly initiating precautions to safeguard her impressive financial portfolio as rumors of an impending split with husband Ben Affleck escalate. Insiders claim that the superstar couple could be heading towards a jaw-dropping $600 million divorce just a year into their marriage.

"Lopez retains a glimmer of hope for reconciliation, but she's also getting ready for the worst-case scenario," a source revealed. The multifaceted entertainer, boasting a net worth double that of Affleck's, did not establish a prenuptial agreement with the "Batman" actor prior to their hasty Vegas wedding last July. Now, Lopez is eager to secure a postnuptial arrangement, insiders disclose.

"They were so enamored with each other that they overlooked the practicalities and plunged headfirst into matrimony - a decision she now sees as flawed," the source revealed.

As reported by The National ENQUIRER, the couple's growing tensions reached a peak at the L.A. premiere of Lopez's movie "The Mother." Witnesses recall an argumentative Affleck irking Lopez on her celebratory night. The incident mirrored a previous spat at the February Grammys, where a disgruntled Affleck drew public criticism from the star.

"Whenever they argue, it's out in the open. And these arguments are becoming increasingly frequent. It's no surprise she's bracing for the worst," an informant stated.

"Despite the conflict, their love for each other persists. However, Lopez stands to lose a lot more. She trusts that Affleck wouldn't attempt to financially exploit her, but she's erring on the side of caution."

The insider added that the "Love Don't Cost a Thing" singer would be deeply embarrassed if their renewed romance were to dissolve, marking her fourth unsuccessful marriage.

"Should she suffer financial loss on top of that, her self-esteem may never rebound," the source remarked.

Sources have reported to The ENQUIRER that Affleck yearns for some space from his assertive wife and more time with his friends, including Matt Damon. He is reportedly ready to take any measures necessary for some peace.

"Affleck is seeking tranquility and distance from the ongoing disputes," the insider disclosed. "He's exhausted with the constant quarrels and would sign any document presented to him at this point!"
