Gwen Stefani, 51, surprised country fans on Tuesday during CMA's Summer Jam event in Nashville when she joined her new husband Blake Shelton onstage for a performance of their duet "Happy Anywhere."

Shelton, who continued to play guitar, introduced his wife by saying, "Gwen Stefani Shelton!" as the crowd started to clap.
