Gwen Stefani and Blake Shelton celebrated Super Bowl 58 debuted their new duet “Purple Irises” live during a Super Bowl LVIII TikTok Tailgate event in Las Vegas.

Shelton, 47, joined Stefani, 54, on Sunday as the musical couple sang for the large live crowd at the tailgate event.

The couple dropped their new song on Friday, adding to their growing list of collaborations. Last year, they rerecorded the iconic 1984 ballad “Love Is Alive” for The Judds tribute album.

The song goes: “But if someone comes along and tries to / Love you like I do / Don’t know what I’d do / Don’t want to lose you,” she sings, later adding: “No, I never knew a love like this. Now we’re picking / Purple irises.”
