Gwen Stefani And Gavin Rossdale Take Their Kids To Jessica Alba's Daughter's Birthday

Celebrity children have to stick together!

Gwen Stefani and Gavin Rossdale took their sons to Jessica Alba's daughter Honor's fifth birthday yesterday. Who knew that Kingston and Zuma rubbed tiny elbows with Honor and Haven? Celebrity stylist Rachel Zoe's husband, Roger Berman, and his son Skyler also attended the star-studded birthday bash.

The fashionable family looked the epitome of rocker chic as they walked to Jessica's Los Angeles home. Gwen donned a plain white tank, boyfriend jeans, and sexy black heels with chunky silver chains. Gavin also sported his signature look: a black tee, funky pants, and high tops. Their children have evidently inherited their unique sense of style. Little Zuma wore trendy tangerine jeans, while Kingston stepped it up a notch with belted white jeans, a collared salmon shirt, and brown boots. After the party, Gwen and her men visited her parents' house.
