Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".

Rebecca Renee Black (born June 21, 1997) is an American pop singer and dancer who gained extensive media attention with the 2011 single "Friday". Her mother paid $4,000 to have the single and an accompanying music video put out as a vanity release through the record label ARK Music Factory. The song was co-written and produced by Clarence Jey and Patrice Wilson of Ark Music Factory. After the video went viral on YouTube and other social media sites, "Friday" was derided by many music critics and viewers, who dubbed it "the worst song ever." The music video received around 167 million views, causing Black to gain international attention as a "viral star", before being removed from the site on June 16. Black re-uploaded it in her own channel three months later.

Rebecca Black was born on June 21, 1997, in Irvine, California. She is the daughter of John Jeffery Black and Georgina Marquez Kelly, both veterinarians. She is of Mexican, Spanish, Italian, English, and Polish descent. An honor student, Black studied dance, auditioned for school shows, attended music summer camps, and began singing publicly in 2008 after joining the patriotic group Celebration USA.^{[citation needed]} In 2011 Black left public school in favor of homeschooling, both in response to constant verbal bullying at school and in order to focus more of her time on her career. Black later said that her main reason for the move to homeschooling was more for career reasons rather than the bullying.
