Joe Jonas is one proud dad. The 31-year-old singer has recently been spotted wearing a necklace with his daughter's name while hanging out with his brothers Nick and Kevin Jonas in New York City.

Jonas Brothers' fans were delighted to see the trio having fun, with many of them liking and leaving positive comments on the photos Joe posted on Instagram.

But what really stole people's attention was one of the jewelry pieces worn by Joe that had a locket with his daughter Willa's name engraved inside of it.

The necklace, which had a tiny diamond on the outside, was from Pattaraphan, according to Page Six. Joe wore it with a pearl pendant necklace and a pearl bracelet, which were also from the same brand.

It appears that the "Toothbrush" singer, who is all set to embark on a tour with his brothers, does not want to part with his darling princess, so he has decided to carry a piece of her with him across the country.

The DNCE frontman welcomed his daughter with his wife Sophie Turner on July 22, 2020, only a year and a couple of months after their 2019 wedding.

Shortly after Willa was born, a source close to both Joe and Turner told US Magazine that the couple was already planning to have their second child.

"They are really excited to expand their family," the insider revealed in December 2020. "Having the baby has made them really close and want to have a large family together."

Joe and Turner celebrated Willa's first birthday last week, shortly after their short-yet-PDA-filled Parisian trip.

The couple's sweetness no longer comes as a surprise to fans. Last month, Joe shared how he and Turner got into Lego building amid the quarantine and how this newfound hobby of theirs helped them strengthen their relationship.

It wasn't easy at first, considering how different their approaches were in their chosen activity. But they still emerged victorious despite the challenges. In fact, the couple built Lego versions of the Batmobile and Harry Potter's "Wizarding World."

"At first we argued about it and then it was like, she loves her organization and it's completely different from the way I would build it: 'You do you; I'll be here for support. So then I became moral support; I'll make the cocktails for us," Joe said in an interview.
