"Part of Me" is a song by American singer Katy Perry, released as the lead single from Teenage Dream: The Complete Confection. It was written by Perry and Bonnie McKee, with production and additional writing by Dr. Luke, Max Martin, and Cirkut. The song was not included on the original edition of Teenage Dream because Perry felt that it did not fit the composition of the album. A demo of the song leaked online in late 2010, amid speculation that the lyrics were directed to the singer's ex-boyfriend Travie McCoy. "Part of Me" was re-worked and officially released on February 13, 2012, through Capitol Records with artwork by art director Gavin Taylor and photography by Mary Ellen Matthews.

The 54th Annual Grammy Awards were held on February 12, 2012, at the Staples Center in Los Angeles being broadcast on CBS honoring the best in music for the recording year beginning October 1, 2010 through September 30, 2011. LL Cool J hosted the show. It was the first time in seven years that the event had an official host. Nominations were announced on November 30, 2011, on prime-time television as part of "The GRAMMY Nominations Concert Live! – Countdown to Music's Biggest Night", a one-hour special broadcast live on CBS from Nokia Theatre at L.A. Live. Kanye West received the most nominations with seven. Adele, Foo Fighters, and Bruno Mars each received six nominations. Lil Wayne, Skrillex, and Radiohead all earned five nominations. The nominations were criticised by many music journalists as Kanye West's My Beautiful Dark Twisted Fantasy missed out on a nomination for Album of the Year despite being highly critically acclaimed and topping many end of year charts. West's album went on to win Best Rap Album.
