In a joint statement posted to their social media pages, Kristin, 33, and Jay, 36, shared photos of the couple together during happier times and wrote that their split comes due to the fact that they have simply grown apart.
Kristin shared a photo of her and Jay walking together with their arms around one another while on vacation. The former NFL quarterback posted a more formal pic of the two as they looked ready for a night out.
Both wrote that they have much "love and respect for one another" and expressed gratitude for their decade-long relationship.
The celebrity couple married in 2013 and share three children, Camden Jack, 7, Jaxon Wyatt, 5, and Saylor James, 4. The family had been quarantining in the Bahamas for the past several weeks, but returned to their Nashville home last Monday, per TMZ.Kristin and Jay met in 2010 during a Chicago Bears presentation and began dating. Within a year, they were engaged, but their initial engagement was called off in 2011. The couple reconciled and married in June, 2013.
In her 2016 book, Balancing In Heels: My Journey to Health, Happiness, and Making It All Work, Kristin revealed that it was she who ended the engagement because "a few things needed to change" in the relationship, and Jay needed to see how serious she was. While Kristin admitted she was "dying inside" during the breakup period, she shared that she knew she didn't want to be a traditional stay-at-home mom while Jay was traveling with the NFL.
"If I stayed at home, I wouldn't be happy," Kristin wrote in her book, per Us Weekly. "And would probably end up resenting Jay for it."
Kristin explained that couples therapy saved the relationship after they learned how to communicate better. The mom-of-three also dished that she and her husband continued to occasionally see their therapist even after they were married.
During their time together, the couple's careers thrived. Jay served as quarterback for the Chicago Bears and the Miami Dolphins, while Kristin became an author and an entrepreneur. The couple also appeared together on Kristin's E! reality show, Very Cavallari.
After Jay retired from football in 2017, Kristin told Entertainment Tonight that the couple's roles had "shifted" with Jay at home with their kids more while she was out working.
"It's been interesting. We've really completely shifted roles, so it's just been trying to navigate this new normal," Kristin said last year.
The Hills alum explained that the couple's relationship worked because she and her husband could "make each other laugh." She also said they had a lot of "trust" in one another.
News of the famous couple's split comes one day after Kristin celebrated the third anniversary of her jewelry brand, Uncommon James. The former MTV star revealed that she started the company as a "side hustle" while she was a stay-at-home mom and that it turned into a full-blown business.
