The two took the stage to perform Sheeran's hit "Thinking Out Loud"
The dapper pair, who were joined by Questlove on the drums, performed Sheeran’s “Thinking Out Loud” and Mayer could barely contain his eyebrows as he jammed out on his pink guitar.
Mayer’s been a fan of the Brit’s since he caught him in concert last year.
“You could break Ed Sheeran’s talent into about six equal pieces and still have six very talented and successful artists,” Mayer wrote on Twitter in August.
Sheeran got the words “kool guy” on his right arm, while Mayer now sports a small cat head on his chest. Rad, guys. Just rad.
Sheeran was nominated for album of the year, best pop vocal album and best song written for visual media.
