Since Pharrell Williams is joining The Voice this fall, it's only natural that NBC would use "Happy" in a promo for the singing competition's new season.
In the 30-second clip, we see Pharrell and fellow Voice newbie Gwen Stefani posing and sharing laughs with returning coaches Blake Shelton and Adam Levine. Gwen and Adam are also teaming up musically; she appears on Maroon 5's upcoming album V.
The seventh season of The Voice begins September 22.
Gwen and Pharrell are taking over the rotating chairs from Shakira and Usher.
