The "Bones" hitmaker has posted a selfie of the two singers, masked up, on Instagram on Wednesday (10Mar21) and made it clear fans could expect a collaboration on music's big night.
"We'll see you at the Grammys," she captioned the shot, tagging Mayer's Instagram page.
Maren's song "The Bones" is nominated in the Best Country Song category.
Meanwhile, The Weeknd was snubbed despite his stellar 2020, during which he broke chart records with his album "After Hours" and single "Blinding Lights", which this week chalked up a full year in the Billboard Hot 100 top 10.
"The Grammys remain corrupt. You owe me, my fans and the industry transparency...," he slammed the Recording Academy following the nomination announcement.
The main event will be followed by a star-studded TV special which will be hosted by Common.
Dubbed "A Grammy Salute to the Sounds of Change", the gig is set for March 17. The line-up include Cynthia Erivo, John Fogerty, Yolanda Adams, Leon Bridges, Eric Church, Andra Day, Patti LaBelle, Terrace Martin, Brad Paisley, Billy Porter, LeAnn Rimes, Chris Stapleton, and Emily, Emilio and Gloria Estefan.
