It's shaping up to be one of the biggest gatherings of music royalty in history.
RadarOnline.com has already told you about the artists who have been scheduled to perform at the Grammy Awards on February 8, names like Jennifer Hudson, the Jonas Brothers, Lil Wayne, Paul McCartney, Katy Perry, Radiohead, Carrie Underwood, and Kanye West.
Now you can add U2, Kid Rock, Rihanna, Robert Plant, and Alison Krauss to that list.
The organizers have also announced just a few of the presenters, who add star-wattage if no particular musical aptitude to the event: Jack Black, Samuel L. Jackson and Gwyneth Paltrow.
The ceremony will be seen live on CBS.
