The buzz about ABC's Oscar broadcast is starting in earnest, and yesterday it was announced that Kristin Chenoweth, the adorable Olive Snook on Pushing Daisies, has been tapped to sing one of the Academy Award nominated songs, "That's How You Know" from the film Enchanted, according to the Baltimore Sun. Kristin will be joined by Marlon Saunders, who played the Central Park Calypso singer in the movie. By the by, Enchanted's star, Amy Adams, will also be singing on the show. She's doing, "Happy Working Song," another nominated song from the Disney hit. FYI, that's the sing-along tune she did in the film with cockroaches, rats and other happy vermin. You can just imagine Walt Disney spinning in his grave, can't you?
