Gwen Stefani just dropped her new, Pharrell-produced single, 'Spark the Fire,' and it is hot!

The super upbeat track showcases the heart of Gwen's talents -- her totally unique voice, fast-paced rhymes and super funky, almost reggae-like style. The 'Voice' judge is always crazy vivacious and bold, so even though she has yet to drop a lyric or music video for the track, we're already envisioning lots of neon and bright colors when we hear this song.

The thumping tune -- which is filled with a handful of well-placed OMGs -- only gets even more hyped up on the chorus, as Gwen shouts, "Who got the lighter? Let’s spark the fire!" Because if there is one thing that Gwen Stefani can do, it's get us totally pumped up and ready to rock out to her new jam.

Spark that fire and listen to Gwen Stefani's new single above!
