Gwen Stefani will launch her debut solo tour this fall, with support from Interscope labelmates the Black Eyed Peas. The Harajuku Lovers arena outing will begin Oct. 16 in Phoenix and has dates on tap through Nov. 10 in Houston. Sources say Stefani has yet to settle on which musicians will back her on stage.

In an interview with Billboard last fall, the No Doubt lead singer expressed reservations about touring without her band. But she apparently warmed to the idea after six months' worth of occasional live performances, including last December at the Billboard Music Awards.

"Touring is something I've done a lot of in my life, and right now it's about doing stuff I've never done before -- like dancing to my own song in a club," Stefani told Billboard. "But I can't picture myself touring without No Doubt."

The artist will be out in support of her solo debut, "Love, Angel, Music, Baby," which peaked at No. 5 on The Billboard 200 and has sold 2.4 million copies in the United States, according to Nielsen SoundScan.
