Katy Perry, Katheryn Elizabeth Hudson

Katy Perry appeared at the 2010 MTV Video Music Awards on September 12, 2010. She was nominated for two awards and presented the award of "Best Male Video" with Nicki Minaj to Eminem. On September 14, she returned to her old high school, Dos Pueblos High School, where she performed a short set for the school's students. Perry performed "Hot n Cold" with Elmo from Sesame Street, which was originally to appear on the forty-first-season premiere of the educational children's program on September 27, 2010. However, four days before the scheduled airing, Sesame Workshop announced, "In light of the feedback we've received on the Katy Perry music video ... we have decided we will not air the segment on the television broadcast of Sesame Street, which is aimed at preschoolers. Katy Perry fans will still be able to view the video on YouTube." The main reason was that parents complained about what appeared to be a great amount of cleavage shown by her dress. Perry shot the video for Firework in Budapest in September 2010. An open casting call drew an unprecedented 38,000 applicants. She proceeded to perform at a concert in Budapest on October 1, her first concert in Central and Eastern Europe. Perry has announced her own fragrance to be released in autumn of this year, named "Purr". It will come in a cat-shaped bottle, and will be available through Nordstrom stores. 'Teenage Dream led Perry to nominations four awards at the 2011 Grammy Awards: Album of the Year, Best Pop Vocal Album, Best Female Pop Vocal Performance for "Teenage Dream", and Best Pop Collaboration with Vocals for "California Gurls". Following the Grammys, Katy Perry released the fourth single from her album "Teenage Dream", "E.T." The single was a remixed version featuring Kanye West. The music video for E.T. was directed by Floria Sigismondi and features Shaun Ross as the main love interest.
Musical style and themes
Perry has a contralto vocal range. Because of her low vocal range, she lowers the key of many of her songs while singing live in order to perfect her sound. Among Perry's musical influences are Alanis Morissette, pop rockers Cyndi Lauper, Pat Benatar, Joan Jett, Shirley Manson, and Freddie Mercury, the late frontman of the British band Queen. Growing up listening to gospel music, Perry had few references when she began recording songs. Asked by the producer with whom she would like to collaborate, Perry had no idea. That night, she went with her mother to a hotel. Inside, she turned on VH1 and saw producer Glen Ballard talking about Morissette; Ballard produced Morissette's Jagged Little Pill, the album that had a "huge influence" on Perry. She told her initial collaborator that she had decided to work with Ballard. The producer arranged a meeting for her and Ballard in Los Angeles. Perry presented him a song, and a day later she was called. Ballard developed Perry for a few years.
