One Direction made a lot of fans very happy on Tuesday after they announced the tour dates of their 2014 "Where We Are" stadium tour in North America.

The British singers made the announcement about their 21-city tour live on ABC's "Good Morning America" Tuesday morning. The tour, which will be presented by Nabisco, will kick off on Aug. 1, 2014 in Toronto, Ontario, and continue on until Oct. 5 and wrap up in Miami, Florida.

Tickets for the Live Nation-promoted North American shows go on sale on Dec. 7 but pre-sale tickets will start on Dec. 3 and be available to Citi card members who RSVP via Facebook. Additional dates will also be announced at a later time.

"We simply can't wait to be back in North America touring and to see our fans," says the group's Niall Horan in a press statement. "It's going to be absolutely huge!"

One Direction currently just released their third studio album, "Midnight Memories," which spawned the hit singles "Best Song Ever" and "Story of My Life." Within 24 hours of its release, it shot to No. 1 in 97 countries around the world.
