The bros Joe, Kevin and Nick were as emotional as anyone, as they turned to Twitter to share their excitement. "This was ten years ago almost to the day, and today my brothers and I have released our new album #happinessbegins thank you to everyone who stood by us every step of the way. We love you. This is for you," Nick tweeted.
Kevin and Nick even shared some baby-faced throwback video because, well, why not.
Happiness Begins features the Billboard Hot 100 leader "Sucker", its top-5 followup "Cool," and its been trending through the night. Judging by the flood of memes and comments, you'd think the JoBros had saved 2019.
