Gwen Stefani is roaring back into action with a variety of projects, after laying low this year following the birth of her first child. According to her Web site, Stefani is "hard at work" on new material with an eye on releasing her second solo album before the end of the year.

The as-yet-untitled set will include a number of Pharrell Williams's collaborations that didn't make the cut on Stefani's 2004 debut, "Love.Angel.Music.Baby, including the Slim Thug-featuring "Breakin' Up."

According to Stefani's site, a concert DVD, "Harajuku Lovers Live," will also arrive before the end of the year. The film was shot at Arrowhead Pond in Stefani's hometown of Anaheim, Calif., and was directed by Sophie Muller.

Finally, this fall will see the release of eight dolls inspired by the album and tour that are reflective of "the distinctive style and personality which have made Gwen Stefani an icon," her site says. The dolls will be bundled with interchangeable outfits as well as Stefani posters, trading cards and other accessories.
