The Chainsmokers has been teasing their fans on social media about a major announcement they are going to make. True to their words, it is a big surprised when they revealed that their first ever full-length album and an arena tour are about to come.

Coldplay first hinted the major announcement The Chainsmokers is going to make. "Excited for @thechainsmokers' album; I've heard some songs and I love them," the group tweeted. Later, the DJ duo confirmed the news on their Twitter account. "Hey Pack, guess the cats out of the bag. We are doing this for you!" they shared while posting the British rock band's tweet.

However, the official release date of The Chainsmokers' album is not part of the group's major announcement. But, Columbia Records chairman and CEO Rob Stringer told Billboard that it will be out in early April. To recall, the "Roses" hitmaker once said that the possibility that they will release an album is up to their fans and with this confirmation; they evidently heard their followers cry.

Moreover, The Chainsmokers' arena tour will be called "Memories: Do Not Open" and they are set to go across North America for 40 nights of performances starting April until June. Aside from their first album, they also unveil their latest single "Paris," according to USA Today. The general ticket sales will be on Feb. 3 via Ticketmaster while the presale ticket will be available at 3 p.m. through Citi's Private Pass website.

"NEW TOUR + NEW ALBUM + NEW PRODUCTION = OUR MOST AMAZING SHOW EVER - TICKETS ARE GONNA FLY, PRESALE 3PM ET / 12PM PT," The Chainsmokers tweeted along with their tour's schedule. Meanwhile, the group, too, will be seen at the upcoming Grammy Awards as they are nominated for best new artist and a three-year Las Vegas residency. Here, they are set to perform in Wynn Nightlife venues exclusively until 2019.
