The Jonas Brothers Bring Out Kirk Franklin, Jimmy Fallon, and Big Rob at First Shows of New Tour

The Jonas Brothers are back on tour, and they're keeping things spicy with a few surprise guests. The brothers kicked off their 2023 tour, aptly titled The Tour, with a sold-out performance at Yankee Stadium on Aug. 12, and the three-hour, 60-plus-song show was a mix of nostalgic favorites and new songs from their album "The Album," which was released in May.

"The Album" is the brothers' first album since 2019's "Happiness Begins," which they also supported with a major tour. Since then, some of the brothers' lives have changed a lot — Joe welcomed two children with wife Sophie Turner in 2020 and 2022, and Nick welcomed his first child with wife Priyanka Chopra in 2022. Meanwhile, Kevin shares two daughters with wife Danielle Jonas — and the brothers all paid tribute to their children with the track "Little Bird" from "The Album."

The Jonas Brothers' tour comes amid a fabulous summer for live music. Beyoncé's "Renaissance" tour and Taylor Swift's Eras Tour are both on track to earn well over a billion dollars, per The New York Times, and they've both awed fans and attracted numerous stars. Like the Jonas Brothers, Swift has also shaken things up by featuring surprise guests including Taylor Lautner, Maren Morris, and Ice Spice.

Ahead, check out some of the special guests who've shown up at the Jonas Brothers' latest tour so far.

Fallon surprised fans when he hopped onstage at the Aug. 13 show and joined the brothers in singing "Mr. Brightside" by The Killers. "How would you all like to be in the world's biggest karaoke party for two minutes?" he asked the crowd, per one video.

He commemorated the experience on Twitter later that night, writing, "Huge thanks to @jonasbrothers for giving me the surprise guest spot on 'The Tour' tour. And thank you to @yankeestadium for turning it into the world's biggest karaoke party. This is one of those nights I will never forget."
