Part of Me

Katy Perry的再版专辑Teenage Dream: The Complete Confection中的全新单曲。 "Part of Me" is a song by American recording artist Katy Perry. The dance-pop and pop rock song was written by Perry and Bonnie McKee, while production and additional songwriting was done by Lukasz Gottwald and Max Martin. The song was released as the first single from the re-release of her album, Teenage Dream: The Complete Confection. This song has been plagued with a range of leaks; in late 2010, the entire demo of the song leaked online, with music critics comparing the song to Perry's previous single "California Gurls" (2010) and the lyrics were initially addressed to the singer's ex-boyfriend Travis McCoy. However, Perry later reworked the song and directed it towards her ex-husband Russell Brand with the lyrics "Keep your diamond ring".
