Louisa Rose Allen (born 29 April 1989), better known by her stage name Foxes, is a British singer and songwriter originally from Southampton and now based in London. She is best known for her featured vocals on Zedd's song "Clarity", which peaked at number eight on the Billboard Hot 100 and at number one on the US Hot Dance Club Songs, and "Let Go for Tonight" which entered the UK Singles Chart at number seven on 8 March 2014. On 26 January 2014, she won her first Grammy Award: Best Dance Recording at the 56th Grammy Awards for "Clarity".
On her website, Allen explained the origin of her stage name. Allen's mother had described a “haunting and beautiful” dream in which foxes ran down their street, howling. Allen, who had been attempting to find a suitable stage name, settled on "Foxes". She found the name fitting because it reflected her music: she had titled her first song “Like Foxes Do" and many of her subsequent songs were about animals. She considered training to be a beauty therapist in her hometown of Southampton but moved to London when she was 18, following her sister and brother, and attended the Institute of Contemporary Music Performance. She began doing gigs as "Foxes" in London in 2011.
