Pop singer-songwriter Gwen Stefani performed last night on NBC's The Voice. She performed her memorable hit "Hollaback Girl" off of her 2004 album, Love. Angel. Music. Baby. Stefani strutted her way down the stage while a plethora of dancers did their thing. She sounded just as lively as she did back in the early '00s, as a solo artist. The only difference was her attire, which was still fashionable yet mom-friendly. Singer / producer Pharrell joined her towards the end of the song. The two icons will be appearing as judges for season 7 of The Voice, replacing Christina Aguilera and CeeLo Green.
