A slew of tickets for the Jonas Brothers [ tickets ]' upcoming world tour hit the box office this past weekend, and the pop trio's fans wasted no time snatching them up.

The sibling act sold a combined total of more than 800,000 tickets for upcoming tour stops throughout North America, and posted sellouts in New York; Los Angeles; Chicago; Philadelphia; Washington, DC; Houston; Pittsburgh; New Orleans; Atlanta; Los Angeles; and Edmonton, Alberta, according to tour promoter Live Nation.

In response to the demand, the group immediately rolled out second shows in Los Angeles, Chicago and Philadelphia, as well as Vancouver, British Columbia.

As previously reported, "The Jonas Brothers World Tour 2009" kicks off June 20 in Dallas and will touch down at arenas and stadiums across North America through an Aug. 31 finale in Ottawa, Ontario.

The US jaunt comes on the heels of a short South American leg in mid-May, as well as sold-out shows at Paris' Zenith Arena and London's Wembley Arena in June. The band's new Hollywood Records effort will hit shelves worldwide June 15, just in time for the stateside trek.

Each show will include a massive, 140-foot stage centered in the arena, allowing for better views throughout the venue. Other ambitious features--such as a one-of-a-kind water screen, laser and automated video effects and a giant crane over the audience--are also expected to wow the mostly female crowd.

The Jonas Brothers' world-tour announcement comes nearly two weeks after the debut of their new Disney movie, "Jonas Brothers: The 3D Concert Experience." The pop trio celebrated the new release with moviegoers, jetting around to select US cities and surprising fans with impromptu performances.
