Gwen Stefani and her Harajuku Girls are set to take on the country, and those of you who want to Holler Back can pick up tickets tomorrow. Sales for the singer’s 40-date tour begin Saturday, Feb. 10, for dates starting April 21 and running through June.

Lady Sovereign, a British MC, will be traveling along with the crew, joining Akon who appeared on “The Sweet Escape” single. Stefani’s latest release of the same name came out in December to rave reviews, so far the only teaser that has been released is “Wind It Up.” Visitors to Stefani’s Website can see the video for “The Sweet Escape” or just listen to the next single.

Stefani is diversifying her portfolio, as she is not only a new mother, but is breaking into the DVD market as well. The release of “Harajuku Lovers Live” shows off what her last tour was like. When these dancers and the ska-punk-hip sound Stefani spits come together, the result is fabulous, and this tour is expected to be a regular sell-out as well.
