The Billboard Music Awards has an impressive live line-up, but it just got that much better. 

Gwen Stefani and her new beau, country singer Blake Shelton, will perform their new duet 'Go Ahead And Break My Heart' together on the night. The event is set to take place on May 22 in Las Vegas. 

The pair recently took their collaboration to 'The Voice' stage and it was met with a warm reception. Shelton, meanwhile, told the press that writing the song with Stefani was nothing short of magical:

"This is one of my favourite songs I've ever written or recorded. It came from a time and place when Gwen and I were beginning our journey together and both experiencing a hard time letting our guards down with each other. The song couldn't possibly be more honest. I'm honoured to have written and to perform this song with the great Gwen Stefani."
