Update: Beyonce, Zac Efron, Vanessa Hudgens and Judd Apatow are in
Beyonce will sing again
Yes, none other than Sasha Fierce (TM) herself will appear on the stage of the Kodak Theater. No, she won't be accepting an Oscar (how silly), she'll be singing in Hugh Jackman and Baz Luhrmann's showstopping number. Reports indicate she was rehearsing with the Aussies earlier this week in New York City. Ms. Knowles previously sang a medley of nominated songs from "Dreamgirls" in 2007 with Best Supporting Actress winner Jennifer Hudson.
