During Monday's episode of The Voice, Gwen Stefani performed her latest single "Let Me Reintroduce Myself" as a tribute to some of her most iconic eras. With lyrics reminding us that "it's not a comeback," Stefani even took it all the way back to No Doubt in a full-circle moment. "It was just a full circle, back to my roots, I know what kind of music I want to make," Stefani previously told Zane Lowe on Apple Music. "And I want to make music that makes people feel happy." Happiness is certainly the effect that the new single had on her fiancé, Blake Shelton, who couldn't help but sing along during her performance. You can experience the single's nostalgia for yourself with the full performance above.
