During Monday's episode of The Voice [1], Gwen Stefani [2] 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 [3] in a full-circle moment. "It was just a full circle [4], 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 [5], who couldn't help but sing along [6] during her performance. You can experience the single's nostalgia for yourself with the full performance above.
