It's official — the Jonas Brothers are getting back together. Yes, really.

Nick, Joe and Kevin Jonas will be joining James Corden for a weeklong takeover event on The Late Late Show next week. As the above preview teases, they'll be introducing their new single "Sucker," bringing back old favorites like "Burnin' Up" for Carpool Karaoke and doing lots of sketches and stunts on the show. And yes, there'll even be a round of "Spill Your Guts or Fill Your Guts," so prepare for some major tea spillage.

The JoBros will be on the show from Monday, March 4 to Thursday, March 7, and fans can expect to hear the story behind their decision to reunite on day one.

As Nick reveals in the teaser, this has been in the works for some time now. "It's nice to finally be able to tell somebody," he says. "We've kept this a secret now for almost seven, eight months. This is basically our first performance back."

The full roll-out of "Sucker" will happen on Friday, March 1 at 12 a.m. ET via Republic Records.

The Jonas Brothers disbanded back in 2013, and the trio went on to do different things: Nick did some more acting in shows like Scream Queens and Kingdom, as well as releasing a solo album and co-founding a record label; Joe headlined the new funk band DNCE and starred on Australia's version of The Voice, and Kevin continued his reality stardom with Married to Jonas.

Now, they've clearly been able to resolve their creative differences. The JoBros are back! Here we go...

The Late Late Show With James Corden airs weeknights at 12:37 a.m. ET on CBS.
