UPDATED Grammy performer list

The Grammys have announced that EMINEM, LIL WAYNE, DRAKE and BLINK-182 drummer TRAVIS BARKER will team-up for a, quote, "special performance" at this year's ceremony, which will air this Sunday night on CBS.


--It's unclear what they will be performing . . . but the lineup of rappers is close to the all-star group that did Drake's "Forever" track . . . only minus KANYE WEST.


(--There's nothing to suggest Grammy producers intentionally kept Kanye off-stage. We don't even know if Kanye will be there. He is up for a few awards.)


--LADY GAGA will also perform. She'll open the show with a surprise guest. The "New York Post" thinks it'll be ELTON JOHN, but we don't know that for sure.


--Previously announced performers include: Mary J. Blige and Andrea Bocelli, Beyoncé, the Black Eyed Peas, Dave Matthews Band and Taylor Swift, Bon Jovi, Green Day, Lady Antebellum, Maxwell, Pink and the Zac Brown Band.


--Plus, there will be a MICHAEL JACKSON tribute . . . featuring Celine Dion, Jennifer Hudson, Smokey Robinson, Carrie Underwood and Usher.
