Jonas Brothers announce 'Happiness Begins' tour for first album in almost a decade

Shows start in August, but their "Happiness Begins" album is out in June.

It’s official: the Jonas Brothers have announced a new tour to support their first album in almost a decade.

The recently-reunited sibling trio -- Nick, Joe and Kevin -- will embark on their 40-city "Happiness Begins" tour this summer. The tour kicks off Aug. 7 in Miami and wraps up Oct. 20 in Los Angeles.

Bebe Rexha will join them as a special guest on most of the dates and singer Jordan McGraw will also perform throughout the tour.

"We're so excited to announce this tour and get in front of our fans again!" the Jonas Brothers said in a statement.

The JoBros added, "We can't wait for everyone to see what we have planned!"

Tickets go on sale to the general public starting Friday, May 10 at LiveNation.com.

The band's upcoming album, "Happiness Begins," goes up for pre-order today. It drops June 7.
