Katy Perry Shines on Letterman

California Gurl Katy Perry performed her new album title track and latest single, “Teenage Dream,” last night on Late Show with David Letterman. It’s easy to lose one’s luster when standing next to this sensational pop-rock star, but Perry’s guitarists held their own thanks to their gorgeous Gretsch guitars.

Letterman also interviewed Perry, discussing her engagement with Russell Brand, how she went from singing gospel music to showing “side boob” in her recent photo shoot with Rolling Stone and what her minister parents think of it all.
