Exclusive Concert, Which Will Follow the Taping of Katy’s LATE SHOW with DAVID LETTERMAN Appearance and Coincide with the Release of New Album, Teenage Dream, Will Be Streamed Across a Variety of CBS Online Properties and VEVO

Katy Perry, two-time Grammy nominee and one of pop’s biggest breakout stars, joins the CBS Interactive Music Group for an exclusive “Live on Letterman” webcast concert, Tuesday, Aug. 24 (live 8:00 PM, ET/5:00 PM, PT).  As a part of the ongoing concert series, Katy will perform the live webcast concert from the historic Ed Sullivan Theater and will play a few of her biggest hits, as well as new songs from her eagerly anticipated second album, Teenage Dream, which will be released the same day as her “Live on Letterman” performance.

Through this interactive collaboration between television, radio and the Internet, fans can connect with their favorite talent in a multiplatform setting, accessible on-air, online and on-demand.  CBS will promote and broadcast the webcast across the Company’s multiple assets, with the live concert streaming on the LATE SHOW website (www.cbs.com/late_night/late_show) and airing that night on select CBS RADIO stations throughout the country.  Additional access to live and on-demand video of the concert will be available through CBS Television Station websites, TV.com, ETonline.com and theinsider.com, while Last.fm and mp3.com will promote and drive tune-in through CBS.com.  Furthermore, as part of CBS Interactive Music Group’s partnership with VEVO, VEVO.com will webcast Katy’s live performance with the archived on-demand broadcast available through a VEVO player on VEVO.com and VEVO on YouTube.

Katy’s exclusive webcast will follow the taping of her appearance on the LATE SHOW with DAVID LETTERMAN, which will be broadcast later that evening, Tuesday, August 24 (11:35 PM-12:37 AM, ET/PT), on the CBS Television Network.

Katy Perry returned to her hometown of Santa Barbara, Calif. for inspiration on her second album, Teenage Dream.  The two-time Grammy nominated singer sold over five million copies of her debut album, One of the Boys, and her latest single, “California Gurls,” is setting her up for a repeat success.  Her whimsical pop songs “I Kissed a Girl,” “Hot N Cold,” “Thinking of You” and “Waking Up in Vegas” have sold more than 22 million digital tracks and mobile products worldwide.  Because Katy writes her own material, her lyrics are filled with truth and an infectious will to have fun.  Those efforts have won her Best New Act at the Europe Music Awards, Best Pop Video at the MTV Japan Awards and International Female Solo Artist at the Brit Awards.
