And while a source says there were some "rough" moments, The Hills alum, 34, and the former NFL player, 38 — who share three kids, Camden, 8, Jaxon, 6, and Saylor, 5 — have found peace with their decision.
"Kristin's worked hard to get back on good terms," says the source. "They've got each other's backs." The two even shocked their fans when they posted a photo on their Instagram, where they were seen standing next to each other amicably.
The exes proved it earlier this year when they seemingly found themselves in a feud with Southern Charm's Madison LeCroy. "Kristin thought her comments were a ploy for attention,” explains the source. "Mocking Kristin and Jay backfired, because they remained united."
"The world is full of users. 10 years. Can’t break that," the two captioned their Instagram post, which sparked reconciliation rumors among their fans and followers. In the picture, Cutler could be seen holding the camera for a selfie while Cavallari leaned against him.

"They are friends and single. They will always have each other's back no matter what," a source told PEOPLE.
Cavallari and Cutler called it quits in April 2020 after seven years of marriage and a decade together. The blonde beauty cited marital misbehavior and irreconcilable differences as the reasons that led to their divorce.
According to an insider, the twosome “fell out of love and grew apart.”
While she and her ex husband may remain cordial, Cavallari's life is anything but drama free. The fan-favorite is sure to bring the heat as she's set to make an appearance on the juicy new season on The Hills: New Beginnings, which airs Wednesdays at 9 p.m. ET on MTV.
