The singer reportedly hated the closeness between the former couple, who married in 2005 and welcomed three children together before announcing their split in 2015.

In the midst of her divorce from Ben Affleck, Jennifer Lopez posted a new video on her Instagram page in which she flaunts her bikini body as if to show her ex what he's missing.

New revelations have emerged about Lopez and Affleck's broken marriage, and it turns out that a famous third party unwittingly contributed to the collapse.

According to OK! Magazinea source revealed that there was tension between Lopez and Affleck's ex-wife, Jennifer Garner, as the singer "felt threatened" by her throughout her marriage to the "Argo" actor.

"J.Lo has felt threatened by Jen Garner for almost her entire marriage," the insider said. "It drove her crazy the way Ben would run to her for advice whenever they had a fight."

It's clear that Affleck and Garner have maintained a cordial relationship even after they finalized their divorce in 2018. They've been seen multiple times with their three children, Violet, Finn and Samuel.

The insider said Affleck likes "spending time with Jen and their kids" because it's "much more comfortable than trying to handle the family business."

"He's so relaxed with her, there's no tension, no pressure, he can be completely himself," the source added.

Apparently, Lopez's alleged concerns took place before she filed for divorce from Affleck. During the time they were having problems, Affleck left their marital home in Beverly Hills and moved into a $100,000 rental house in Brentwood near Garner.

In August, Affleck and Garner were seen accompanying their daughter Violet to her freshman year at Yale University in New Haven, Connecticut.

They were also seen serving food at Midnight Mission in LA, California on Thanksgiving and reportedly spent Christmas together.

"Jen and Ben were together for Christmas. It's all about the kids," the source said People Magazine. "Jen grew up surrounded by family for the holidays, and she wants the same for her kids."

Meanwhile, Garner is reportedly happy that Affleck is moving on from Lopez and has reportedly expressed her decision to cut ties with Lopez.

"Jen no longer wants to communicate with J.Lo unless it's about the kids," the insider said Daily Mail.

"Her friends feel that she shouldn't have allowed herself to get so involved in helping J.Lo fix her marriage with Ben. Especially considering that Jen sometimes felt against J.Lo during their marriage. Jen is too nice and really wanted help, so she tried," the source explained.

Another source said Old that Affleck has made progress in his efforts to move on from the "Let's Get Loud" singer and is trying to be present for his children with Garner.

"Now that Ben is back to his old routine, he's feeling good about himself," an insider told the outlet. "Spending time with Jen Garner and the kids over the holidays helped him feel like everything was right in his world again."

Although they split, Lopez and Affleck decided to maintain a cordial relationship for the sake of their children.

The exes reunited over Christmas at the members-only Soho House in West Hollywood, where they dined together and even exchanged gifts.

the source said Page Six that they "have every intention of continuing to be in each other's lives despite not being romantically involved."

The insider added, "Ben and Jennifer are still connected and communicating when it comes to their kids."

The "Atlas" actress rang in the New Year in Aspen, Colorado with her mother Guadalupe, sister Linda, manager Benny Medina, children Emma and Max and other music producers and stylists.

In a recent Instagram post from a snowy getaway, she made sure to show Affleck what he's been missing, flaunting her figure in a black string bikini with gold accents.

The video also featured other moments from her icy getaway, including decorating a Christmas tree, dancing with pals in what appears to be a bar, and going sledding with a friend.

"We'll be back, Aspen," Lopez captioned the Instagram post.
