Lily Rose Beatrice Cooper (née Allen; born 2 May 1985), known professionally as Lily Allen, is an English singer, songwriter, actress, and television presenter. She is the daughter of Keith Allen and film producer Alison Owen. Allen left school when she was 15 and concentrated on improving her performing and compositional skills. In 2005, she made some of her recordings public on Myspace and the publicity resulted in airplay on BBC Radio 1 and a contract with Regal Recordings. Her first mainstream single, "Smile", reached number one on the UK Singles Chart in July 2006.

Her debut record, Alright, Still, was well received, selling over 2. 6 million copies worldwide and brought Allen a nomination at the Grammy Awards, Brit Awards and MTV Video Music Awards.

She began hosting her own talk-show, Lily Allen and Friends, on BBC Three. Her second studio album, It's Not Me, It's You, saw a genre shift, having more of an electropop feel, rather than the ska and reggae influences of the first one.

The album debuted at number one on the UK Albums Chart and the Australian ARIA Charts and was well received by critics, noting the singer's musical evolution and maturity. It spawned the hit singles "The Fear" and "Fuck You".

This success saw her receive the Brit Award for British Female Solo Artist at the 2010 Brit Awards. Allen and Amy Winehouse were credited with starting a process that led to the "year of the women" media label in 2009 that saw five female artists making music of "experimentalism and fearlessness" nominated for the Mercury Prize.

In 2009, Allen announced that she would be taking a hiatus from musical activities. In 2011, she launched her own record label.

In 2013, Allen revealed that she had begun working on her third studio album, which was later titled Sheezus. On 12 November 2013, Allen premiered the video for her first original song since 2009, "Hard out Here", which was released as a single five days later.
