Beyonce will probably use that beautiful voice of hers to perform "Halo"; it's more Grammy-like and has the biggest chance to win I think; I would love to hear her sing "Once In a Lifetime" which is also nominated and is from the Cadillac Records soundtrack. As for the Oscars lip synching commment (@MORE TRUTH), Beyonce has perfomance after performance of live singing and dancing and you pick that one performance to criticize where she was doing ballroom songs & choreography at the same time that were of a completely foreign genre for her (as a newcomer to those types of performances I think she pulled it of nicely). What about her other Oscar performances where she sang beautifully or rendition of "At Last" for the first couple's first dance. She sang those and countless other performances live. And all the comments about the Grammy noms are unfair since she earned those nominations for recordings on two albums, "I Am..." and "Cadillac Records Soundtrack." Some of you are making uneducated comments and probably don't even realize that she is nominated for a beautiful song like "Once In a Lifetime" from Cadillac Records (along with a nomination for her rendition of "At Last"). It's not all about "Single Ladies" although it was a huge hit and deserves to at least be nominated if not win. "Halo" is a beautiful vocal performance and also deserves its nominations. Whitney can't carry a tune anymore. Beyonce is clearly one of the best contemporary artists and in my opinion SHOULD have more nominations than artists like Lady Gaga or even Taylor Swift (I don't hear anyone complaining about their multiple nominations.)
