Katy Perry - Part Of Me (Video clip)

"Part of Me" is a single by American artist Katy Perry, recorded as the best song from Teenage Dream: The Complete Confection. Music was composed by Perry and Bonnie McKee, with directing

and additional writing by Dr. Luke, Max Martin, and Cirkut. The single 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 single 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.

A dance-pop and power pop single with a distinctive house beat, it has been compared to Jessie J's 2011 single "Domino" and Perry's 2010 songs "Firework" and "California Gurls". Its lyrics describe a female protagonist who declares herself as unbreakable and strong following a break-up. Many critics theorized that the lyrics addressed Perry's divorce from Russell Brand, although Perry stated it was not about him since it was written in early 2010.
