Gwen Stefani took her three sons shopping for costumes in Los Angeles over the weekend, and it looks like Kingston, Zuma and little Apollo scored some pretty sweet costumes. We couldn't tell what all of the outfits were, but someone's definitely going to be a pumpkin ... How cute!

After going on a Halloween shopping spree, the group grabbed frozen yogurt at Menchie's, and as always, Gwen looked like a million bucks. We're not obsessed with the black streak in her hair, but she definitely knows how to pull it off...

In other news, the singer will be dropping some new tunes before the end of the year! Stefani’s manager Irving Azoff spoke at a panel at New York’s Advertising Week, and he revealed that Gwen has been working on new tracks for her upcoming solo project with Pharrell Williams and Diplo. The project is slated for release in December, and we'll get a peek at her new single when she performs it on this season of NBC’s The Voice.

Can't wait!
