(Photo: http://photos.prnewswire.com/prnh/20130820/LA66923) Pepsi and MTV are partnering to conclude the 2013 "MTV Video Music Awards" with an epic and show-stopping finale in which Katy Perry will perform her new worldwide smash single, "Roar," live from an undisclosed location in Brooklyn when the VMAs air on August 25 at 9pm ET/PT. To build excitement and anticipation for Katy Perry's forthcoming new album, PRISM, MTV and Pepsi today are launching a pioneering tweet-to-unlock and social voting program that encourages fans to decide on one of two new Katy Perry songs from the new record that will be released early on iTunes. Fans who tweet #KATYNOW will unlock clues around two of the album's tracks, including the song titles and select lyrics. Once fans have unlocked the song clues by reaching a certain number of tweets, Pepsi and MTV will unveil the two never-before-heard preview clips via pepsi.mtv.com. The voting frenzy will continue through the VMA telecast as Pepsi and MTV give fans a chance to sample the songs and decide which one will be released early by tweeting, using one of two unique hashtags to vote. The winning song, which will be released on Tuesday, September 17 via iTunes album pre-order, will be revealed live on MTV just moments before Katy's VMA performance. Also on VMA night, Pepsi will gift fans with a free download of "Roar" by simply joining Pepsi Experience Points (PXP), Pepsi's rewards platform. "We're excited to support a talented and iconic artist like Katy Perry to offer her fans these amazing opportunities," said Chad Stubbs, Senior Director, Marketing for PepsiCo. "We hope through the continuation of our Iconic Summer program to give consumers a VMA experience that they will never forget." Pepsi will continue to deliver on its promise to fans for an Iconic Summer filled with memorable experiences, including a VIP all-access trip to NYC for the VMAs and an epic Pepsi pre-party experience prior to Katy Perry's performance. Other program elements of Pepsi's partnership with the VMAs include reporting from the red carpet, sponsor billboards, MTV News pre-and-post show Pepsi Program hits, and MTV VMA content on Pepsi Pulse.
