Jonas Brothers Celebrate the ‘Truly Insane’ Billboard 200 No. 1 Debut of ‘Happiness Begins’

“It’s just the beginning!!!”

As the Jonas Brothers' triumphant return continues, so does their excitement. Just after news broke that the sibling trio's Happiness Begins album debuted at No. 1 on the Billboard 200 on Monday (June 17), Nick and Kevin took to social media to celebrate their latest achievement and thank fans for the support.

"I don’t even know what to say. This is so incredible," Nick wrote in an Instagram post. "We set out to make a record that embodied the happiness we feel after having been through so much together. The fact that this music has connected with people in this way means the world us. Thank you for believing in us."

Nick also tweeted that he was "blown away" by the first-week numbers — 414,000 equivalent album units — which Kevin seconded. "I can’t believe this! Thank you so much everyone truly insane! It’s just the beginning!!!," Kevin Jonas wrote on Twitter and Instagram.

Happiness Begins, which the Jonas Brothers released on June 7, marked the biggest week 2019 for an album, besting the first-week numbers Ariana Grande's Thank U, Next by more than 50,000. It's also the largest week for a group since One Direction's Made in the A.M. in 2015 and the biggest week for a pop album since Taylor Swift's reputation in 2017.

The Jonas Brothers will be taking Happiness Begins on the road on the Happiness Begins Tour, which starts in August. Click here for tickets, and take a look at Nick and Kevin's celebratory posts below.
