It seems as if one of Katy's old, but hot, unreleased songs will be the first single off her upcoming rerelease, "Teenage Dream: The Complete Confection"!  The song is "Part of Me" and is rumored to have dubstep, a feature, and electro added to the final version!  The single cover is above and to check out more information on the upcoming rerelease check here, here, here, especially here, and lastly here!  Can't wait for her Grammy performance of her new single and all the fun things we will be getting in the upcoming months!
UPDATE:  There might be new or different news coming!  Katy just tweeted, "The TRUTH will set you free."  Maybe "Truth" is a song title!?  Any way, I'm excited!
UPDATE: Check out the official amazon preview of Katy Perry's upcoming single, "Part Of Me", which leaked last January.  It sounds similar to the demo, but I hope the rest of the song is spiced up.  It will be a hit no matter what though! According to the website is should be released February 21!
