Stepping out to help her husband celebrate his birthday, Gwen Stefani was spotted at Madeo restaurant in Beverly Hills yesterday (October 30). The “Hollaback Girl” songstress looked “rocker chic” in a black and white shawl with a very bright bra shining through from underneath. Gwen’s husband of 7 years, Gavin Rossdale, turned 42 years young yesterday, but it sounds like the musician is more excited about Halloween this year than his birthday.
