Gwen Stefani and Blake Shelton performed at the 2016 Billboard Music Awards Sunday night at the T-Mobile Arena in Las Vegas. The real-life couple rocked the event, singing their duet “Go Ahead and Break My Heart.”

Shelton, 39, took the stage first, and was joined a few moments later by Stefani. The 46-year-old singer wore a sheer crystal-encrusted gown with natural makeup and her long blond hair down with loose waves. The two looked at each other lovingly throughout the performance, and walked off the stage hand in hand at the end of the song.

This is the second time Stefani and Shelton performed “Go Ahead and Break My Heart” on television. The duo first sang the song, off Shelton’s new album, “If I’m Honest,” on NBC’s “The Voice” earlier this month.
