As if the Grammy Awards needed more celeb wattage when it airs this Sunday, the ceremony has just added Neil Diamond, Stevie Wonder, M.I.A., and Motown legend Smokey Robinson to the roster of performers.
There will also be a jam session featuring Buddy Guy, B.B. King, John Mayer and Keith Urban celebrating the work of the late R&B legend Bo Diddley.
In case you've lost track, performers also include Miley Cyrus, Taylor Swift, Kanye West, U2, Kid Rock, Rihanna, Kenny Chesney, Coldplay, Jennifer Hudson, Jonas Brothers, Lil Wayne, Paul McCartney, Radiohead, T.I., Justin Timberlake, Carrie Underwood, and Jay-Z, among many others.
And that doesn't include all the star presenters who don't plan on singing.
RadarOnline will have a list of the winners for you as-it-happens!
