Grammy bosses have confirmed that Madonna will perform at the music award show this weekend. It was rumored last week that the singer would take the stage with one of today's hottest singers, perhaps joining Beyonce for a showstopping set.

Details haven't been released regarding who the material girl will be performing with on Sunday.

Green Day's Billie Joe Armstrong is another last-minute addition to the roster of performers. He will join country star Miranda Lambert for a tribute to Everly Brothers star Phil Everly, who died earlier this month.

Previously announced performers include:


Jay Z

Sara Bareilles

Katy Perry

Taylor Swift

Blake Shelton

Daft Punk with Stevie Wonder

Pharrell Williams with Nile Rodgers

Chicago with Robin Thicke
