Hollaback Girl -- Gwen Stefani turns 44 years old today!
No Doubt first hit the scene in 1986, with Gwen as the group's frontwoman. Before the ska-pop band made it big with their '95 album "Tragic Kingdom," Stefani shared some awesome duets with Sublime -- lending her vocals to tracks like "Saw Red."
The group became radio gold with singles like "Just a Girl" and "Don't Speak." But in 2004, the blonde bombshell decided to go solo and dropped her hit album Love. Angel. Music. Baby. -- she topped the charts with songs like "Rich Girl" and "What You Waiting For."
Today, Gwen has taken a break from her music career to focus on her family with Bush frontman Gavin Rossdale. The rocker pair have been married since 2002, and have two adorable boys together. There's even rumors that Gwen is expecting her third child!
Oh ya -- the pop star also has two successful clothing lines, L.A.M.B. and Harajuku, in addition to a slew of fragrances.
She's definitely doing well for herself -- and we can't wait to see what Stefani does next. Click "Launch Gallery" above to see more pop stars then and now!
