Music's biggest night just keeps getting bigger. The 51st annual Grammy Awards, which air on Sunday night on CBS, have added yet another round of performers to the roster: Kanye West will appear with Estelle (most likely for their Song of the Year nominee "American Boy"). Miley Cyrus and Taylor Swift are teaming up. Adele, Chris Brown and Sugarland have been added to the list. And there will be a tribute to legendary Motown group the Four Tops featuring Jamie Foxx, Ne-Yo and original last living original member, Duke Fakir.

The latest additions join a list that already included Jennifer Hudson, the Jonas Brothers, Coldplay, Katy Perry, Radiohead, Rihanna, T.I. with Justin Timberlake, U2, Carrie Underwood, Kid Rock, Paul McCartney with special guest drummer Dave Grohl, Kenny Chesney and Robert Plant & Alison Krauss. The show will also feature a solo performance from Lil Wayne, the night's most nominated artist, and he's expected to throw down his verse on T.I.'s "Swagga Like Us," alongside Jay-Z, Tip and Kanye.

The addition of Ne-Yo to the live roster of talent on the show means that all five of the contenders for Album of the Year — which also include Radiohead, Coldplay, Lil Wayne and Robert Plant & Alison Krauss — will now be performing on the show.

Among the newly added presenters are Sheryl Crow, Queen Latifah, T-Pain, Al Green, actor Jay Mohr and late-night talk-show host Craig Ferguson. They join a list of previously announced presenters that includes Gwyneth Paltrow, Samuel L. Jackson, Jack Black, Duffy, Josh Groban, Simon Baker and jazz musician Charlie Haden.
