Bonnie Leigh McKee (born January 20, 1984) is an American singer-songwriter, formerly signed to Reprise Records. She released her debut album Trouble in 2004, which was a minor success. The single "Somebody" was included in the soundtrack to the 2004 comedy film Win a Date with Tad Hamilton!. As a songwriter McKee has enjoyed success writing international hit singles for Katy Perry ("California Gurls", "Teenage Dream", "Last Friday Night (T.G.I.F.)" and "Part of Me"), Taio Cruz ("Dynamite") as well as Britney Spears ("Hold It Against Me").

McKee was born in Vacaville, California, and spent her formative years in the Seattle area. Upon moving to Seattle, she joined the Seattle Girls Choir. She toured Europe in 2000 as a member of its top Prime Voci choir, including a concert in Rome at the request of Pope John Paul II. She recorded two albums with the choir, including "Jackson Berkey Meets The Seattle Girls' Choir" and "Cantate 2000".

McKee's youth was somewhat unconventional. She attended the private high school, The Bush School, but amid failing most of her classes, and at the requests of parents concerned with the influence McKee would have on her classmates, she was kicked out before she could finish her freshman year. However, the week after her expulsion, The Bush School did allow her to participate in a program in which she spent a week in a recording studio with her classmates. This demo contained several songs that ended up on her album Trouble, including the title track and "When it All Comes Down", the latter being inspired by her rejection from the school.

Cher Lloyd (born 28 July 1993) is an English recording artist. Lloyd rose to fame when she finished fourth in the seventh series of The X Factor. Shortly afterwards, Lloyd was signed by Simon Cowell to Sony Music subsidiary Syco Music.

Cher Lloyd's debut single "Swagger Jagger" was released in June 2011. Despite receiving negative reviews, the single entered at number one on the UK Singles Chart and number two on the Irish Singles Chart. Her second single "With Ur Love" was released on 31 October, featuring Mike Posner, and peaked at number four in the UK, and number five in Ireland, preceding her debut album Sticks + Stones, which peaked at number four in the UK Albums Chart and number seven on the Irish Albums Chart.

Cher Lloyd used to live in Malvern with her parents Darren and Dina, and three younger siblings brother Josh, and sisters Sophie and Rosie. Lloyd attended Dyson Perrins CE Sports College, where she studied performing arts. She also attended theatre arts school Stagecoach.

Lloyd had previously auditioned for The X Factor twice before (when the minimum age was lower) singing ballads, but did not make it through. Lloyd has previously performed at holiday camps and said she gets a mixed reaction to her music, but was a big hit with x-factor judge at the time Cheryl Cole. She remarked on their similarity and Cheryl went on to support her throughout the show. She auditioned singing the Keri Hilson version of "Turn My Swag On". At bootcamp she sang a rap version of "Viva La Vida" adding lyrics she claimed to have written herself, but this was disputed and reports claimed she took them from a song by rapper Swizz Beatz. At the judges' houses she performed "Cooler Than Me" but suffered from tonsillitis and was unable to complete her song. She was given a second chance, but broke down sobbing and could not complete the song. Despite this, she was still picked as one of the final three girls by mentor Cheryl Cole.
