Beyonce & Katy Perry Set To Perform @ 2015 Grammys

Beyonce & Katy Perry Set To Perform @ 2015 Grammys

Well, the 57th Annual Grammy Awards just got that much more fierce.Katy Perry and Beyoncé have been added to the show's already jam-packed performance lineup at what is almost the 11th hour—considering the 2015 Grammys is Sunday!

Billboard was first to report the addition of Perry, who can rest easy on her high tiger after presiding over the most-watched Super Bowl halftime show in history. (So of course the Recording Academy wanted in on that...) Per the music mag, the Prism artist, who's nominated for two Grammys this year, will be singing her ballad "By the Grace of God" and, of course, could have more tricks up her sleeve.

Meanwhile, Common spilled the beans regarding the very special addition to his and John Legend's planned performance of "Glory," their massively popular song from Selma, which is the frontrunner to win the Oscar for Best Original Song in a couple of weeks.

"We do have an incredible introduction to our performance," Common told Us over the weekend. "A segue into our song ‘Glory,' as a tribute to Selma, being done by the great Beyoncé. That's one of the greatest talents you can have, helping us segue into it. To co-create a performance with someone like her. It's good."

Queen Bey, who's tied for the top of the pack with six nominations (including Album of the Year and Best Music Film), will kick off the already hotly anticipated collaboration with the gospel song "Take My Hand Precious Lord."

And the must-see and who'd-a-thunk-it pairings keep on coming: The Recording Academy also confirmed this morning that Album of the Year nominee Beck will take the stage with Chris Martin; Mary J. Blige will join Sam Smith (we can feel the slow-burning angst already); Best New Artist nominee Brandy Clark will now be making her Grammys performance debut with country veteran Dwight Yoakam; John Mayer, Herbie Hancock and Questlove will joinEd Sheeran; Juanes, who's up for Best Latin Pop Album, will presumably sing a hit from Loco de Amor; pianist Lang Lang will team up with someone on one of the past year's catchiest tunes; and, last but not least, Sia will do her thing, presumably while wearing a mask and surrounded by long-limbed dancers.
