Next week's Grammy Awards show is shaping up to be one of the best in recent memory with Madonna and Beyonce now expected to perform.

Rumor has it that Madonna could contribute guest vocals to a performance from one of the night's nominees. Who that could be is anyone's guess. Some previously scheduled performers that Madge could cozy up with include Lorde, Taylor Swift, Macklemore and Ryan Lewis, and Kendrick Lamar with Imagine Dragons.

Beyonce on the other hand is expected to offer her first televised performance since releasing her surprise self-titled album last month. The album is still doing well on the charts and could receive an additional boost from her appearance. Beyonce is also up for one Grammy this year as a featured artist on her husband Jay Z's 'Magna Carta...Holy Grail' track "Part II (On the Run)."

Madonna and Beyonce will most likely join an already all-star lineup that also includes a Beatles reunion with Paul McCartney and Ringo Star, Pharell Williams and Stevie Wonder, Daft Punk and Niles Rodgers, and Metallica and concert pianist Lang Lang.
