Hartley, 42, cited irreconcilable differences as the reason for their divorce, according to documents filed Friday and obtained by PEOPLE. The This Is Us star listed the date of separation as July 8, 2019. However, the pair attended the Emmy Awards together on Sept. 22, the Veuve Clicquot Polo Match in Los Angeles on Oct. 5, and a Hollywood Reporter-sponsored pre-Golden Globes party on Nov. 14.
Reps for Hartley and Stause have yet to comment.
According to a source close to the couple, Hartley and Stause, 38, have “been having trouble for a while.”
“In many ways, they’re somewhat fundamentally incompatible,” the source told PEOPLE. “Chrishell is really ready to just settle down and be a wife and stay-at-home mom and was hoping to start a family relatively soon. Justin wants that but also doesn’t think it has to happen in the near future and is at a point in his career where he wants to really be able to explore all the options that are coming his way. He’s reached a new level of fame thanks to the show and he doesn’t want to close many doors right now, and that’s not the path Chrishell is looking to take. She thought babies would happen soon after they got married, but it just hasn’t worked out.”
Hartley and Stause tied the knot in an intimate ceremony at Malibu’s Calamigos Ranch on Oct. 28, 2017 — four years to the day after they met.
Hartley was previously married to soap star Lindsay Korman from 2004 to 2012. The couple still has joint physical custody of their daughter Isabella, 15.
Though they met in passing early on in their careers, sparks flew when one of Stause’s Days of Our Lives castmates, who was a pal of Hartley’s, introduced them.
“We met up at a concert and talked all night,” the actor told PEOPLE in 2017. “I drove her home and called the next day. We haven’t been apart since. I knew right away [and] was like, ‘Oh boy, here we go.’”
“The next day I texted my friend: ‘I found him,’” said Stause.
After more than two years of dating, the couple announced their engagement in July 2016. Fifteen months later, they tied the knot.
The couple exchanged handwritten vows in front of 75 of their closest family and friends in a rustic and romantic ceremony. Stause stunned in a Monique Lhuillier gown, while Hartley oped for a black Brooks Brothers tux.
“They don’t make them any better than Justin, and I could not be more thrilled to officially be Mrs. Hartley!” Stause told PEOPLE once married.
TMZ was the first to report news of the split.
