Blake Shelton and Gwen Stefani, made a virtual appearance on The Tonight Show Starring Jimmy Fallon on Monday night (April 13), where Gwen shaved Blake’s head adding a new detail…Jimmy Fallon’s initials.

“I’m literally putting your initials in my head right now, Jimmy, I’m not kidding,” Shelton jokes in the video as Stefani works on his head with a trimmer. “She just said they’re not showing up very well because of the grey.”

“You are so Tiger King right now,” Jimmy Fallon joked to Blake Shelton after she finished.

Blake and Gwen also performed an acoustic version of “Nobody But You.”
