Katy Perry will release a special edition of her double-platinum certified album 'Teenage Dream' on March 27th, 2012. The first run of the release will feature a limited edition lenticular cover. 'Teenage Dream: The Complete Confection' includes all 12 tracks from the original version of Katy’s second album, including the singles “California Gurls,” “Teenage Dream,” “Firework,” “E.T.,” “Last Friday Night (T.G.I.F.),” and “The One That Got Away,” which all peaked at No. 1 on the Billboard Pop Songs chart.
It also features three brand new songs as well as versions of “E.T” featuring Kanye West, “Last Friday Night (T.G.I.F.)” featuring Missy Elliott, and a moving acoustic version of “The One That Got Away” produced by Jon Brion. None of these alternative versions have ever been available on a physical CD until now. Also included on The Complete Confection is a 7 minute Tommie Sunshine megamix featuring all six No.1 hits.

"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,” states Katy.
