Gwyneth Paltrow, Florence & The Machine Academy Awards Performances 2011

Academy Award winner Gwyneth Paltrow — who played an alcoholic singer in the musical drama Country Strong and received a standing ovation at last year’s Country Music Awards — will take the stage at this year’s Oscars to perform “Coming Home,” which is up for the Best Original Song prize, the Academy of Motion Picture Arts and Sciences announced on Friday.

In addition to Gwyneth, Mandy Moore, Randy Newman, Zachary Levi, and British newcomer Florence Welch of Florence & The Machine will also take the Oscar stage, singing the tunes that are up for this year’s Best Song Oscar. Newman will perform his Toy Story 3 theme “We Belong Together.” Welch and Rahman will perform “If I Rise” from 127 Hours. Moore, Levi, and Menken have been tipped to perform “I See the Light,” featured on the Tangled soundtrack.

Final ballots were mailed Wednesday to the more than 5,700 voting members who will decide the winners of this year’s Oscars.

The 83rd Annual Academy Awards — hosted by James Franco and Anne Hathaway — will be presented Feb. 27 at the Kodak Theatre and broadcast live on ABC.
