UPDATE: Madonna and Queen Latifah will join Macklemore & Ryan Lewis at the GRAMMYs for a special performance of the gay rights' anthem "Same Love."
The GRAMMYs are taking the tagline "music's biggest night" seriously this year. Madonna confirmed she's rocking Sunday night's awards show, where she's set to take the stage with one of the 2014 nominees.
The GRAMMYs also announced that Green Day frontman Billie Joe Armstrong and country singer Miranda Lambert will sing a tribute to late rock legend Phil Everly on Sunday. Armstrong and Norah Jones recently covered an entire Everly Brothers album.
This news comes after Spin revealed Dave Grohl is teaming up with Nine Inch Nails, Queens of the Stone Age and Fleetwood Mac's Lindsey Buckingham for a presumably ear-shattering performance that will wrap the awards show this Sunday.
As for the opener, everyone seems to think Beyonce and Jay Z have that honor. Either way, they're both confirmed to perform at the GRAMMYs, and this will be Beyonce's first TV performance in support of her surprise 2013 album.
And don't forget the stellar lineup of previously announced performers hitting the stage at the 56th Annual GRAMMY Awards: Katy Perry, Taylor Swift, Daft Punk, Macklemore & Ryan Lewis, Metallica, Kendrick Lamar, P!nk & Nate Ruess, John Legend, Robin Thicke, Lorde and R&B genius Stevie Wonder.
The night will feature plenty of fascinating collaborations: Metallica will rock out with Chinese pianist Lang Lang, Thicke will play with classic rock outfit Chicago and Wonder is playing with Daft Punk & Nile Rodgers. Kendrick Lamar will hit the stage with Imagine Dragons, while former Beatles Paul McCartney and Ringo Starr are set to duet together.
