Gwen Stefani rocked the mic for Spotify's huge end of the year bash -- singing hits from her solo career and time with No Doubt ... and TMZ has the video.
The Spotify celebration, dubbed "A Totally Normal Party for 2021," went down Tuesday at an event space in Los Angeles ... with Gwen stealing the show.
Gwen performed for 45 minutes and her set featured some of her most famous songs ... including "Just a Girl," "Hey Baby," "The Sweet Escape," "Spiderwebs," "Hollaback Girl," "Don't Speak," "It's My Life" and "Rich Girl."
The first act on stage was the USC Trojans marching band ... but Gwen was the big draw here.
Spotify's year-end party comes on the heels of their 2021 Wrapped unveiling ... you've definitely seen people share their top Spotify songs and artists on social media ... and at one point, Gwen joked about hearing she was a top Spotify artist.
Of course, that's just a joke and Gwen knows it ... but she's right about this ... she can say whatever she wants because as she told the crowd, "It's my f****** show!!!"
