But first, take the Grammy Prediction Quiz and get ready with 10 things you simply gotta know about tonight's big show:

1. J.Lo will be presenting, and if we're lucky, she'll wear something along the lines of "nothing," like in 2000.

3. There will be talk of Haiti. Lots.

4. Lady Gaga and Elton John—together!—will open the show with some kind of crazy medley.

5. There will be a tribute to the Michael Jackson—in 3D! Grab your gloves and fedoras.

6. You might even see Jackson's kids on stage.

7. Travis Barker is retooling his posse to look like Drake, Eminem and Lil Wayne. Oh, or maybe they're all just performing together. Either way.

8. Stephen Colbert will be joining the party as a presenter and nominee. Little known fact: That hot piece of man can get down.

9. The cast of the new Broadway show American Idiot will join up with Green Day for a performance about idiots. That are American.

10. Possible reunion of nominees Taylor Swift and Kanye West? We can only be so lucky.
