This is an S.O.S.
Joe, 34, stated that "the marriage between the parties is irretrievably broken," per the court documents obtained by E! News.
He asked for "shared parental responsibility" with Sophie, 27, and said a "parenting plan should be established" for their daughter Willa, 3, and another daughter, 14 months, whose initials were only listed as "D.J." in the docs.
The Jonas Brothers singer also asked the court to uphold their prenuptial agreement from April 2019.
His split with the Game of Thrones alum comes after speculation emerged about their relationship status over Labor Day Weekend. At the time, Sophie's rep declined to comment on the actress' personal life when reached by E! News, while Joe's rep had no immediate comment.
Yet, the two recently celebrated Joe's 34th birthday together in August. In honor of the special day, Sophie shared a selfie of the two posed in green striped PJs in the mirror of a walk-in closet. She captioned the Instagram Story post, "Happy birthday handsome."
That same month, the Dark Phoenix actress supported Joe as he and the Jonas Brothers kicked off their Five Albums. One Night. The World Tour with a concert at New York City's Yankee Stadium. At the time, Sophie even shared a sweet Instagram photo showing her kissing Joe's hand, captioning the post with Jonas Brothers lyrics, "long long New York nights."
The former couple married in a small Las Vegas ceremony in May 2019 after dating for two and a half years. The following month, they tied the knot again in a larger wedding in France in front of family and friends.
Throughout their relationship, Joe and Sophie kept many details about their romance private.
The reason? As the "Cake By the Ocean" singer explained to Mr. Porter in November 2022, "I want to feel like an open book. But when we started dating, I realized that I didn't have a ton of stuff that was just for me. And in the end, it makes me a better person to have something for myself."
Though he did acknowledge that his career naturally puts him in the spotlight.
"I come back to why I do this," he told the outlet. "I'm still so grateful to do this, so if being in the public eye comes with some of that drama and the eye rolling and if you have to swat some beef with a person you met once, then so be it."
"Besides, if it means I get to wake up and do this another day," Joe noted, "then it's all worth it."
As for Sophie, she's given rare insight into her and Joe's family over the years.
In May 2022, before welcoming the couple's second child, the actress even addressed their growing brood.
"It's what life is about for me–raising the next generation," she shared with Elle UK. "The greatest thing in life is seeing my daughter go from strength to strength."
"We're so excited to be expanding the family," she noted. "It's the best blessing ever."
