The Oscars could be quite the musical this Sunday – and host Hugh Jackman won't be the only one belting out the tunes. Several sources tell E! Online's Marc Malkin that the Oscars will feature performances by Beyonce, and "High School Musical" stars Zac Efron and Vanessa Hudgens.
Amanda Seyfried and Dominic Cooper, who starred together in "Mamma Mia!" are also supposed to sing on the stage at the Kodak Theater if their scheduling conflicts can be resolved.
