The Jonas Brothers gave fans a special memory that will last a lifetime during a recent concert.

The trio brought their Greetings From Your Hometown Tour to Utah on Saturday (September 13), but they did more than just perform some of their biggest hits. According to a fan video shared online, they were tasked with helping with a pregnant fan's gender reveal, per People.

"I'm very excited about this," Joe Jonas said, holding an envelope and speaking with a fan in the crowd. "Let's find out shall we?"

Before getting to the big reveal, however, the group performed their song "Little Bird," a track from their 2023 record The Album that pays tribute to each of their children. Kevin Jonas is a dad to daughters Alena, 11, and Valentina, 8, with wife Danielle Jonas, Joe shares daughters Willa, 5, and Delphine, 3, with ex-wife Sophie Turner, and Nick Jonas and wife Priyanka Chopra Jonas are parents to daughter Malti, 3.

After joking that he "forgot" about the major announcement he promised to make, Joe declared "show me the baby" as he opened the envelope, quipping, "Place your bets now. Just kidding. You can't do that here." He then revealed that the fan is having a baby girl, causing the stage to light up pink and the crowd to cheer as he offered his congratulations.

The JoBros are the latest artists who have been asked to assist in revealing the sex of an expectant fan's baby during a concert. Other musicians who have taken up the task of creating a special, lifelong memory include Adele, Ed Sheeran and Beyoncé, to name a few.
