Gwen Stefani is set to release new music with the help of her old pal Pharrell Williams. Pharrell produced Gwen's upcoming single called "Spark The Fire," and the pair talked about how the lyrics came together in the studio on "The Ellen DeGeneres Show."
Meanwhile, Gwen told Ellen that Pharrell "keeps bouncing in and out of [her] life in such an amazing way" and that every time they cross paths "something really crazy happens." It's been about ten years since Pharrell produced Gwen's solo mega hit "Hollaback Girl."
The new song will officially have its debut with a performance next Monday on NBC's "The Voice," on which they both serve as coaches. A joint video for the track is expected out soon as well, which they have gave fans a sneak peek at! Check it out below:
