It was announced that actress Sandra Bullock will be the first recipient of a new People's Choice award - Favorite Humanitarian.

Swift and her boy band boyfriend Harry Styles have been spotted numerous times together - most recently kissing on New Year's Eve - and many hoped to see them together on the red carpet for Wednesday's show. However, though both Swift and the One Direction singer are nominated for awards that night, a 1D representative confirmed that the band will not be in attendance at the award show.

Swift is nominated for Favorite Female Artist, Favorite Country Artist and Favorite Song For "We Are Never Ever Getting Back Together." One Direction is nominated for Favorite Breakout Artist, Favorite Album, Favorite Music Fan Following and Favorite Song for "What Makes You Beautiful."

Fellow U.K. band the Wanted will be present at the award show, and are also nominated for the Favorite Breakout Artist award.

Jennifer Lawrence graced the cover of the February 2013 issue of Vanity Fair magazine as "The World's Most Desirable Woman."

She was given the title based on results from an international poll released by AskMen.com. "'The Hunger Games' star climbed to the top of the list from No. 47 last year. Lawrence bumped last year's winner, Sofia Vergara of "Modern Family," down to No. 12.
