Kristin Cavallari of Very Cavallari fame found out about her ex-husband Jay Cutler's long-time affair with his best friend's wife after the husband caught them "hooking up" during a family vacation. Kristin and her ex-sweetheart Jay were married for years before calling it quits. The 35-year-old TV personality and the retired professional bodybuilder, 48, who share children Camden Jack, Saylor James, and Jaxon Wyatt, announced they were going their separate ways in April 2020 after 10 years together.

According to Kristin's divorce filing, she and Jay's relationship suffered many misconducts despite lasting for a decade. The television personality and doting mom accused Jay of inappropriate marital conduct in the filing. She noted that "further cohabitation" was unsafe and improper. The fashion entrepreneur also cited "irreconcilable differences" as the reason behind their split. After filing for divorce, Kristin and Jay were granted joint custody and have been co-parenting just fine. The new arrangement has reportedly made Kristin a better mom.

However, Kristin found out about her ex-husband's long-time mistress amid their ongoing divorce. A source told In Touch that Jay and his children went on a vacation with his friend, who also took his family along. But while everyone set their minds on having the best relaxing time, Jay and his friend's wife wanted some special time of their own, and that was when things got messy. The IFBB pro and his friend's wife were caught hooking up during the getaway. The woman's husband confronted the pair about their affair and discovered that they had been fraternizing for a long time. The source added, "The friend reached out to [ex-wife Kristin Cavallari], so that's how she found out. She just wants to distance herself from all of this."

In the meantime, while Jay is seemingly content with his and his friend's wife's romance, Kristin is more interested in finding love again. Shortly after the "Balancing in Heels" author made her dating plans public, she was spotted getting cozy with Bachelorette's Tyler Cameron while shooting a campaign for her clothing and jewelry line Uncommon James. However, despite the makeout sessions, Kristin said nothing is going on between her and Tyler as she only hired him to play her love interest in the campaign video.

While the Very Cavallari star's romantic affair is unknown, her relationship with her kids improves daily. Meanwhile, it is unclear where Jay stands with his kids amid his recent dilemma, that is, if they know about the situation. Although the children may not be involved, Jay's friend, who already knows the four-time Mr. Olympia winner's affair with his wife, will likely cut ties with him. In addition, Jay's affair with his friend's wife is also likely to cause trouble in the couple's marriage. However, nothing can be concluded yet as only future developments will determine where they all stand. Meanwhile, Kristin and Jay are yet to settle their split since 2020, though a source said the exes' ongoing divorce is close to being finalized.
