Joe Jonas sings Sophie Turner love song at Jonas Brothers concert ...

She’s still his muse.

Joe Jonas sang a love song he wrote for his wife, Sophie Turner, during the Jonas Brothers’ concert Sunday — despite news breaking hours prior that the couple are heading for divorce.

Fans waited with bated breath to see whether the band would keep “Hesitate” on their usual 67-song setlist at the Moody Center in Austin, Texas, during the “Happiness Begins” portion of their Five Albums, One Night world tour.

Once the 2019 track began playing toward the end of the night, the audience erupted with excitement, as seen in videos shared on social media.

Concertgoers were also quick to notice that Jonas, 34, was wearing his wedding ring again during the show after ditching it on previous tour dates.

The DNCE frontman previously described “Hesitate” as a “love letter” to Turner, explaining in the Jonas Brothers’ 2020 “Happiness Continues” concert film, “It’s like my vows before I wrote my vows. It’s my promise to Sophie.”

The ballad includes poignant lyrics like “I promise we’ll figure this out” and “I thank the oceans for giving me you,” the latter of which is a nod to the “Game of Thrones” star, 27, being born in England.

Page Six confirmed earlier Sunday that Jonas and Turner’s four-year marriage is on the rocks, with a source telling us, “Joe is exploring the best options for his future.”

People magazine, meanwhile, reported that the boy bander has retained a divorce lawyer, and TMZ’s sources claimed the couple have had “serious problems” for at least six months.

Neither Jonas nor the actress have publicly commented on the status of their relationship.

The pair started dating in 2016 and got engaged the following year. They eloped in Las Vegas in May 2019 and share two daughters: Willa, 3, and a 1-year-old whose name they have not revealed.
