Gwen Stefani had her sons Kingston and Zuma along at LAX Friday as the trio headed out of town. The singer and designer is heading to New York, where she'll show off her latest L.A.M.B. collection at Fashion Week next Thursday. Last season, she brought her boys along for the show, and even walked the runway hand in hand with Kingston. The No Doubt frontwoman is all about balancing work and family, and has been clocking lots of time with Gavin, Kingston, and Zuma in LA as she puts the final touches on her upcoming album with the band.
