Gwen Stefani Leaving No Doubt Rehearsal | Pictures

Gwen Stefani smiled leaving a rehearsal studio in Burbank yesterday. No Doubt's currently practicing for their upcoming shows in Germany and LA. They're scheduled to perform at the MTV EMAs on Nov. 11, then will jet back to the West Coast to headline seven sold-out shows at LA's Gibson Amphitheatre. The group recently talked about their upcoming gigs, saying, "Everyone is in top form. It's going to be an amazing time and a chance for us to show to the world why we're so proud of our new album. And it's always awesome to do what we love most, which is play live." Hopefully, the gang will be able to take a break from work for some much deserved holiday fun. Gwen's one of our favorite celebrities who dress up for Halloween — and in the past we've seen her step out as Cinderella, a fried egg, and even a cowgirl.
