Gwen Stefani was out and about in London today wearing a newsboy cap and bright-red lipstick. The singer and designer has been hanging out with her sons in England lately, but she's still been hard at work between their family outings to the zoo, park, and aquarium. This week, we had an exclusive preview of Gwen's Harajuku Mini Line, which will be available at Target on Nov. 13. Gwen's turned her focus toward fashion for now, as No Doubt's delayed the release of their upcoming reunion album. The CD was expected to hit stores sometimes this year but the band recently said it wouldn't drop until 2012. Meanwhile, Gavin Rossdale is on the road with Bush in support of their new album, their first release in a decade.
