The No Doubt alum is shown most prominently in the clip, which also features Williams and returning coaches Adam Levine and Blake Shelton in all-black outfits — yet still dressed in their distinct styles. The four performers recently filmed season seven's blind auditions in Los Angeles.

In a joint interview in May, Stefani said of her newly announced post on the show, "I'm trying to pinch myself — is this really happening?" while Williams added of their onscreen reunion, "It's magical, it's serendipitous. We've always had a special connection, and it was always through music that we recognized each other's admiration and the depths [that] there was such potential."

Williams also said about his intended coaching strategy: "My advice is always gonna have a consistent thread of, 'Be you. If it doesn't work for this show, that's OK.' ... You'll see what Gwen and I do. We're gonna take a slightly different approach. All we're gonna do is hold up the mirror and show people how rad they are already."
