Jonas Brothers World Tour 2009

The stage was set up as an in-the-round at the center of the venue measuring 144-feet-wide to allow for better audience viewing. It incorporated many features such as a one-of-a-kind large circular water screen, a giant crane that extends over the audience, laser and automated video effects and a double Lazy Susan at the center stage, consisting of one in the center and an outer one as a ring around the other. It was designed similar to Britney Spears' Circus Tour. The tour used this stage for all of its legs except for the Caribbean and the South America legs of the tour, where they decided to use a normal stage with catwalk instead. ==Support==

Demi Lovato supported them in Europe and also in all their Latin America tour dates. British girl group Girls Can't Catch performed in United Kingdom tour dates. The Wonder Girls, a South Korean girl group, joined the Jonas Brothers in various North American tour dates.
