Hayley Evetts born 4 March 1976 in Birmingham, England is a singer, TV presenter and stage actor. She rose to fame on the hit British TV talent show Pop Idol. She first came to the attention of the public when she appeared on Popstars, the TV show that launched Hear'say and Liberty X. After failing to make either of the groups she returned and auditioned for Pop Idol. She made the final 10 along with Will Young, Gareth Gates and Darius Danesh, eventually coming 5th. The following year she presented Cruel Holiday for Sky TV. She also presented Pop Idol Extra on ITV2 alongside Dane Bowers. In 2003 she won the role of Sandy in Grease The Musical along with Jonathan Wilkes who played Danny. In 2011 she independently released a single, 'Waste My Time'.

Kelly Brianne Clarkson (born April 24, 1982) is an American singer, songwriter and occasional actress. Clarkson came into prominence after becoming the winner of the inaugural season of the television series American Idol in 2002 and later was the runner-up in the television special World Idol in 2003.

In 2003, Clarkson released her debut album, Thankful, which was a commercial success and established herself in the pop music industry. The release of its first single, "A Moment Like This" (2002), broke The Beatles' record for the biggest leap to number one, from 52, in the history of the Billboard Hot 100 chart. After parting ways with her management, Clarkson developed a more rock-oriented music with the release of her critically acclaimed sophomore album, Breakaway (2004), which sold more than 12 million copies worldwide and which garnered Clarkson more worldwide success as a pop rock artist. The album's single, "Because of You" (2005), became the best-selling single by an Idol contestant worldwide. In 2007, Clarkson took full creative control for her third album My December, which had a more rock-inspired sound and was met with controversy and moderate success. Clarkson later returned to a more pop-oriented sound with All I Ever Wanted (2009), which became a commercial and critical success. The album's lead single, "My Life Would Suck Without You" (2009), surpassed "A Moment Like This"'s record for the biggest leap to number one on a single week in the history of the Billboard Hot 100 Chart, a milestone it still holds today. Furthermore, it also became her first number one single in the United Kingdom. Clarkson's fifth studio album, Stronger, was released in 2011, containing elements from synthpop, R&B and country music. The album's single, "Stronger (What Doesn't Kill You)" (2012), became her longest number one single and eventually became her best-selling single in the United States.

William Robert "Will" Young (born 20 January 1979) is a British singer-songwriter and actor who came to prominence after winning the 2002 inaugural series of the British music contest Pop Idol, making him the first winner of the now-worldwide Idols-format franchise. His debut single, "Anything is Possible", was released two weeks after the show's finale and became the fastest-selling debut single in the United Kingdom.

As a teenager, Young studied politics at the University of Exeter before moving to London, where he pursued a musical theatre degree at the Arts Educational School. Although enrolled in a three-year programme, Young put his studies on hold in late 2001 to become a contestant on Pop Idol. After winning the competition the following year, he released his debut album From Now On (2002) which went to straight to number one. Friday's Child (2003) followed one year later and enjoyed greater popularity, eventually going platinum five times in the UK and spawning three top five singles. Achieving similar success, the album's successors include the multi-platinum Keep On (2005) and platinum Let It Go (2008) with his most recent release Echoes (2011) becoming his third UK number-one album.
