Nick, Joe and Kevin Jonas rocked thematically matching red-and-black ensembles as they performed their first new single since getting the band back together, "Sucker," after being excitedly introduced by the night's host, Emma Thompson.
The brothers commanded the stage for their first set of the night, rocking the audience with their supremely catchy single for one of the strongest SNL musical performances of the season thus far.
The song marked the band's first No. 1 on the Billboard Hot 100 chart ever, and proved to be a perfect first single to mark their return to the music scene.
When the Jonas Brothers returned to the stage for their second set of the show, the guys brought all the heat to their slower new track, "Cool."
However, the coolest moment of all came when Joe stopped the single to surprise fans by "taking things back" with a track from their old days, before breaking into a fast-paced performance of their 2008 track, "Burning Up," to close out their second set.
The fun throwback was a great way of showing their fans that they haven't forgotten their past and aren't embarrassed by their old hits.
The brothers also made sure not to miss out on all the fun when it came to the night's sketches, and made a hilarious cameo as a trio of party boys who burned down a rental house in a TV courtroom sketch featuring Thompson, Kate McKinnon and Aidy Bryant as three celebrity courtroom judges who end up adopting the brothers.
Meanwhile, the Jonas Brothers have been gearing up for the release of their new album, Happiness Begins, in June, as well as the launch of their Happiness Begins Tour later this year.
