Katy Perry August 2, 2009

Alt-pop sensation (and California native) Katy Perry hits the stage to support her hit album 'One of the Boys,' which includes the Top-40 hits 'I Kissed a Girl' and 'Hot N Cold.' Perry--who released her first album, the gospel-oriented 'Katy Hudson' in 2001 before switching professionally to her mother's maiden name--worked with a variety of top-name producers and songwriters for 'One of the Boys,' which hit stores in June 2008. Collaborators included former Eurythmic Dave Stewart, Glen Ballard (Alanis Morissette), and Dr. Luke and Max Martin of Backstreet Boys and Britney Spears fame. The singles 'Ur So Gay' and 'I Kissed a Girl' delivered Perry her first tastes of breakthrough fame, with the latter song reaching No. 1 on the US Billboard Hot 100 chart and, as well as on charts in more than 20 other countries.
