Talk about a star-studded Saturday night!

Celebs were out in full force on Long Island this weekend for the Apollo in the Hamptons annual fundraiser in support of the legendary Harlem venue. Jennifer Lopez, Christie Brinkley and others shared Instagram pics from inside the star-studded bash, as the crowd was entertained by music from Gwen Stefani, Lionel Richie, The Roots, Usher, and more!

One of the biggest surprises of the night, however, had the crowd swooning. Stefani’s beau, country star Blake Shelton, made a surprise appearance onstage to join her for a duet at the beginning of her set. Full Prince CEO Desiree Gruber snapped some great front row video of the two making heart eyes at each other during their song “Go Ahead and Break My Heart.”

Stefani was also joined onstage by another one of her fellow Voice judges, Pharrell Williams, who jumped on to help out with “Hollaback Girl” (which he wrote and produced with The Neptunes).
