Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. Perry rose to fame in 2008 with the release of her second album, a pop-rock record titled One of the Boys, and its singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its sapphic themes. Her third album, Teenage Dream (2010), ventured into disco, and was her first album to top the U.S. Billboard 200. It topped the U.S. Billboard Hot 100 with the singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)" while "The One That Got Away" reached number 3 on the chart. The album became the first by a female artist to produce five number-one songs in the U.S., and the second overall after Michael Jackson`s album Bad.

Perry has received many awards, including four Guinness World Records, five American Music Awards, a Brit Award, and a Juno Award, and has been included in the annual Forbes lists of highest-earning women in music from 2011-2017. She is one of the best-selling music artists of all time, having sold more than 40 million albums and over 100 million records globally throughout her career.
