Pepsi sponsoring Katy Perry performance for MTV Video Music Awards

PURCHASE, N.Y. — Pepsi is teaming up with MTV to support a performance by pop star Katy Perry at the 2013 MTV Video Music Awards, from an undisclosed location in Brooklyn Aug. 25.

Pepsi will also hold a tweet-to-unlock and social voting program where fans can access information and audio samples of two songs from Perry's upcoming album, Prism, available Oct. 22. Participants 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 preview clips via pepsi.mtv.com. The voting will continue throughout the VMA telecast as Pepsi and MTV give fans a chance to sample the songs and decide which one will be released early on iTunes by tweeting and using one of two hashtags to vote.

The winning song will be revealed live on MTV just moments before Perry’s VMA performance. Also on VMA night, Pepsi will gift fans with a free download of "Roar" by joining Pepsi Experience Points, 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."
