John Mayer closed out the U.S. leg of his tour on Tuesday with a special guest — girlfriend Katy Perry.

At the Barclays Center in Brooklyn, the crooner brought out his gal pal for an encore performance of their song “Who You Love.”

The pair started and ended the duet with a quick smooch.

The performance came hours after the couple premiered the “Who You Love” music video during their first joint interview on “GMA.”
