Gwen Stefani  had her mom, Patti Flynn, by her side while heading to a Halloween  party in LA on Saturday. Gwen and husband Gavin Rossdale  walked their sons, Kingston and Zuma, to the children's bash, which was also attended by a costumed Sandra Bullock  and her little man, Louis. While the adults went casual for the event, their boys sported cute costumes — Zuma was dressed as the Red Power Ranger, while Kingston and a friend wore their soccer uniforms.
Gwen and her family have been getting into the Halloween spirit for most of the month. They visited a Lake Arrowhead pumpkin patch  recently, where they were joined by Gwen's No Doubt bandmate and former boyfriend, Tony Kanal, and his family. Their trip to the mountains  came just days before Gwen all but confirmed rumors that she and Gavin are expecting their third child. The couple stepped out for the Wallis Annenberg Center For the Performing Arts Inaugural Gala in LA earlier this week, and Gwen, wearing a fringed dress, cradled her baby bump for the cameras  and was all smiles while posing with her man.
