Lily Rose Beatrice Cooper (born 2 May 1985), better known as Lily Allen, is an English recording artist, actress and fashion designer. She is the daughter of actor and musician Keith Allen and film producer Alison Owen. In her teenage years, her musical tastes evolved from glam rock to alternative. Allen abandoned school and concentrated on improving her performing and compositional skills. Afterwards, she created several demo songs and, near the end of 2005, she created a profile on MySpace where she made some of her recordings public.

A contract was signed with the label Regal Recordings, as the views on MySpace rose to tens of thousands. In 2006, she began to work on completing what would be her first studio album and its first mainstream single "Smile" reached the top position on the UK Singles Chart in July 2006. Her debut record, Alright, Still, was well received on the international market, selling over 2.6 million copies and brought Allen a nomination at the Grammy Awards, BRIT Awards and MTV Video Music Awards. She then began hosting her own talk-show, Lily Allen and Friends, on BBC Three.
