Kelly Clarkson will be giving her voice a workout this summer.
The Grammy-winning pop star and original "American Idol" will be on tour from July 7 to Sept. 28, visiting nearly 40 U.S. and Canadian cities, it was announced Thursday.
"This will be the biggest tour I've ever done," Clarkson said in a statement. "It's all about the music — we're bringing extra musicians and we'll be making an arena environment intimate because I want the fans to be part of the show."
Clarkson, whose third album is set for a summer release, will open her tour with the Live Earth concert at Giants Stadium in East Rutherford, N.J. The tour will end in Las Vegas in September.
