The publication reported Jonas has been allegedly caring for their two children "pretty much all of the time" even while on tour with brothers Kevin and Nick Jonas. The trio kicked off their world tour on Aug. 12 in New York and will wrap up in North America on Dec. 9 before resuming the tour in February overseas.
The couple first began dating in 2016 and were engaged a year later.
At the time, Jonas celebrated the happy moment and posted a photo to Instagram showcasing Turner wearing her new engagement ring, with the caption reading "she said yes."

They welcomed their first daughter in 2020, and their second in 2022.
Speaking to British Vogue last year, Turner shared her journey to motherhood.

"I simply cannot leave the house without a snack for her because then my life would be made a living hell and I would get yelled at by my child," she joked.
Jonas told People that he felt "a little less nervous" about welcoming a new addition.
"You really don’t know what to expect … but I’m just excited," he said, noting that children were "such an amazing part of life."
