Joe Jonas, the lead singer of the Jonas Brothers, has filed for divorce from actress Sophie Turner after over four years of marriage, according to court documents obtained by Fox News Digital. The filing took place on Tuesday in Miami Dade County court. The couple, who famously met when Jonas messaged Turner on Instagram, have two children together: a three-year-old daughter named Willa, and a one-year-old daughter whose name has yet to be revealed.

The divorce filing comes as a surprise to many, as the couple had recently sold their Miami mansion, fueling speculation that they were planning to work on their relationship. However, Jonas described their marriage as "irretrievably broken" in the filing, according to a report by People magazine.

Jonas and Turner tied the knot in 2019 in a surprise wedding ceremony at the Little White Wedding Chapel in Las Vegas. They followed it up with a more formal wedding in France the following month. The couple's relationship has been a subject of interest for their fans, with Turner acknowledging that his Jonas Brothers fans and her Game of Thrones fans can be protective of them. However, she expressed that their fans have grown more accepting over time, particularly as Jonas' fanbase has matured.

Turner has frequently spoken about her love and admiration for Jonas. In a 2019 interview with Glamour, she described him as someone who loves her more than he loves himself and who has pushed her to find her own happiness. She credited their relationship for helping her discover her identity beyond acting.

The news of Jonas and Turner's divorce filing comes as the Jonas Brothers are currently on their "Five Albums. One Night" tour. Photos shared on social media show Turner attending their recent concert in Austin, Texas. Despite the divorce proceedings, Jonas shared a photo on Instagram this week showing him wearing his wedding ring.

According to TMZ, Jonas has been taking their children on tour with him while Turner has been filming in the U.K. The court documents reportedly indicate that Jonas is seeking joint custody.

Jonas' two older brothers, Kevin and Nick, are also married with children. Kevin has been married to his wife Danielle since 2009, and they have two daughters. Nick married actress Priyanka Chopra in 2018, and they welcomed a daughter named Malti in 2022. In a previous interview, Kevin and Nick emphasized that they do not give each other advice about family and that they each do things their own way.

Representatives for Jonas and Turner have yet to respond to requests for comment on the divorce filing. This story is still developing.
