This is Brit's first major tour in years---and her first live shows since performing a handful of random, critically panned concerts at the House of Blues in 2007.  The Pussycat Dolls will open on the new tour, which starts March 3 in New Orleans and ends on April 28 in Rosemont, Illinois.

Brit will also perform two London, U.K. shows in June.
