Tonight's Oscar telecast may have featured the most musical numbers in recent memory, so it's no wonder everyone on the red carpet seemed to be itching to belt out a tune.
PICS: Hollywood's New Hires
From Les Miserables star Hugh Jackman to Channing Tatum and pregnant wife Jenna Dewan-Tatum, watch the stars give their best on-the-spot rendition of will.i.am's Scream & Shout featuring Britney Spears.
Even Quvenzhane Wallis got in on the fun, but with a slight twist. Having been announced to play Annie in the Will Smith produced remake, the nine-year-old Oscar nominee sang Tomorrow from the classic musical. The upcoming film is set for a winter 2014 release.
