Gwen Stefani got her start in the music business with the California rock group No Doubt, which formed in 1986.
Their big songs "Just A Girl" and "Don't Speak" are still bangers and continue to hold up as fun singles that showcase Stefani's playful voice.
Their album Tragic Kingdom went diamond, so nothing can take that away from them.
Stefani then decided to hit the road on her own, and she's had a pretty good career of it so far. Stefani is currently a coach on "The Voice," so when Stefani speaks, people listen.
