Gwen Stefani and Pharrell Perform ‘Spark the Fire’ on ‘The Voice’ [VIDEO]

Gwen Stefani seriously showed us how it’s done when she and Pharrell performed her new single ‘Spark the Fire’ on tonight’s (Dec. 1) episode of ‘The Voice.’

She floated into the room on a cartoon cloud — while wearing a onesie with cloud print all over it -- which was totally fitting considering the lyrics to the song: “Hey! Get off my cloud!"

We didn’t think it could get any better, but then Pharrell came out with a sparkler (get it?? 'Spark the Fire'? Exactly.) and it suddenly turned into one of our favorite performances on this season of ‘The Voice.’ The whole thing was super colorful, playful and -- most importantly -- tons of fun. Both Gwen and Pharrell have amazing amounts of energy as performers and they played off each other incredibly.

Not to mention Gwen Stefani is definitely the only person this planet who can pull off that two-toned, black and blonde hair.

Check out their performance of ‘Spark the Fire’ in the video posted above!
