Perry recorded a demo of the track that leaked in full on December 30 , 2010 . The song was rumored to be a leftover cut from her '' Teenage Dream '' recording sessions , and fans speculated that the track might be included in an as-yet-unconfirmed re-release of the LP . This re-release was confirmed in January 2012 , when Perry announced through her official website that the album would contain all twelve songs from the original album , plus three new songs and a remix , and would be released on March 26 , 2012 . Perry 's press release stated : " This is the complete story of Teenage Dream . It was an incredible honor to tie the King of Pop 's '' Billboard '' Hot 100 record , but I 'm moving forward and had a few things left to get off my chest . So this is the complete special edition of my album for my fans . " On February 13 , 2012 , " Part of Me " received an official release as the lead single from the album 's re-release . Perry had planned all along to release the song on the deluxe edition of the album rather than the original , as it did not fit that album 's composition . On February 11 , two days before its worldwide premiere , the song was leaked for a second time with a reworked production and slightly changed lyrics . " Part of Me " was released to most iTunes stores worldwide on February 18 , 2012 , following her performance at the 54th Grammy Awards . In the United States , " Part of Me " was sent to contemporary radio playlists on February 21 , 2012 . The song was released in England , Scotland , Wales , France , and Ireland on March 18 , 2012 under the digital download and CD single formats . Perry revealed via Twitter that all profits raised from the sales of the single would be donated to MusiCares . The photograph by Mary Ellen Matthews that was used on the single cover was part of a photographic essay for Perry 's appearance in episode 710 of the television program '' Saturday Night Live ''
