The two stars joined show veterans Adam Levine and Blake Sheldon for their first promo picture of the new judges.

"First look: Season 7 #HOLLA," the picture was captioned. Stefani is seated in the middle of Williams and Adam Levine for the photo-op, adding a pop of color with her signature red lips while holding a red microphone. Country singer Blake Shelton is behind them, pointing at the newbies while flashing a wide smile.

Stefani is following in the footsteps of Christina Aguilera and Shakira as the panel's sole female judge and shared a pic of herself outside the studio on Tuesday, along with the caption "#workingit on the set."

Usher Tells Gwen Stefani And Pharrell Williams To "Follow His Lead" For Season 7? 

Most recently, former The Voice judge Usher shared a little advice that may help Stefani and Williams achieve success for their new gig.

"[They can] be motivated by the fact that I was able to win The Voice," Usher recently told the The Today Show. "I think that they are both incredible artists, and as long as they are as true in their process of working with talent as they are with their creative, then it should work. They're geniuses.

"For the most part they should just be true to who they are, that's what I did. It was a bit unorthodox... but that was all a process of artist development," he added.

The Voice is set to return this fall on NBC.
