Watershed Music and Camping Festival was B-A-N-A-N-A-S this weekend.
Blake Shelton, who headlined the first night of the 2018 festival at Gorge Amphitheatre in George, Washington, welcomed surprise guest Gwen Stefani in the middle of his set. The country superstar’s girlfriend and No Doubt frontwoman performed her 2005 hit “Hollaback Girl” for the rowdy crowd, and the festival’s official Instagram caught it all on camera.
Gwen has developed a reputation for surprising country fans during her country beau’s sets. In 2016, she joined him onstage at Country Jam to celebrate his birthday with a performance of their duet, “Go Ahead and Break My Heart.” Currently, Gwen is headlining her Las Vegas residency, Gwen Stefani: Just a Girl, at the Zappos Theater at Planet Hollywood Resort & Casino.
Look for Blake when he returns for Season 15 of The Voice, beginning September 24 on NBC.
