Gwen kicked off the show with the fan-favorite "Hollaback Girl."

The mom of three also sang hits from her No Doubt days, including "Spiderwebs," before launching into a cover of Rihanna's hit song "Umbrella."

Other stars on hand to support Gwen were Extra host Mario Lopez.

Of course Blake Shelton was there to support his girl!
