After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry and released her first Internet single "Ur So Gay" that November, which garnered public attention but failed to chart. She rose to fame with the release of her second single "I Kissed a Girl" in 2008, which went on to top international charts. Perry's first mainstream studio album One of the Boys followed later that year and subsequently, became the thirty-third best selling album worldwide of 2008. It was accredited platinum certification by the Recording Industry Association of America, while "I Kissed a Girl" and her second single "Hot n Cold" both received multi-platinum certifications. Her sophomore studio album Teenage Dream was released in August 2010 and debuted at number one on the Billboard 200. The album included hit singles "California Gurls", "Teenage Dream" and "Firework", all of which topped the charts on the Billboard Hot 100.
Perry was credited as a guest judge on the seventh series of the British television show The X Factor; has released a fragrance called "Purr"; and will appear in the upcoming 2011 film The Smurfs. Perry had a long relationship with Travie McCoy; she married Russell Brand on October 23, 2010.
