Is Blake Shelton teaming up with Gwen Stefani on a new duet? That’s the rumor that’s been circulating after Blake and Gwen were spotted in Hollywood on Thursday (6/1) walking into a recording studio together. Entertainment Tonight obtained a photo of the two walking side by side near the studio, leading some to speculate about a possible collaboration. If the rumor turns out to be true, the collaboration would mark the couple’s second time teaming up in the studio following their duet “Go Ahead and Break My Heart” from Shelton’s latest album, If I’m Honest.
