Gwen Stefani's son, Zuma Rossdale, doesn't turn 8 until Aug. 21, but he's already getting a head start on the birthday festivities. During one of Gwen's This Is What the Truth Feels Like tour stops in Austin, TX, on Tuesday, the singer gave Zuma a special shout-out by bringing him out on stage with his brothers, Kingston and Apollo. Not only did Gwen surprise Zuma with a birthday cake, but she even got thousands of fans to sing "Happy Birthday" to him. "Would you guys sing happy birthday with us?" Gwen asked the audience.
Gwen is out on tour until mid-October and currently appears on the cover of this month's Harper's Bazaar issue.
