Louisa Rose Allen (born 29 April 1989), known professionally as Foxes, is an English singer, songwriter, and model.

[8] After her debut single "Youth" was noticed by Zedd in 2012, she was featured on the song "Clarity", which peaked at number eight on the Billboard Hot 100 and won a Grammy Award for Best Dance Recording.

[9] At 18 years old she considered training as a beauty therapist, however her sister persuaded her to move to London to pursue her singing ambitions.

[16] "Youth" and its B-side, "Home", were featured in the American television series Gossip Girl and an EP, Warrior (produced by Samuel Dixon, also known as Sam Kennedy), followed in July 2012, which Foxes promoted with a US tour.

[17][18][19] Paste magazine described Warrior as "a beautifully ethereal EP that warrants all sorts of comparisons, but equally manages to stand on its own two feet",[20] while PopMatters wrote that it was "a powerful, well-rounded set" and Consequence of Sound introduced the singer as "[i]f Florence Welch and Katy Perry had a beautiful, brunette love child".

[23][27][28] In the United Kingdom, "Youth" reached number 12 on the singles chart in October 2013, concurrent to the song's use in a high profile advertising campaign for retailer Debenhams.

[9] A newly recorded version of "Let Go for Tonight", a track previously featured on the Warrior EP, was released as a single in February 2014, charting in the United Kingdom at number seven—Foxes' first top ten hit.

[29] A fourth single, "Glorious", followed in August 2014 and was used in an ITV advertising campaign promoting the network's autumn season of programmes.

[33] During September and October 2014, Foxes served as the opening act for R&B musician Pharrell's Dear Girl Tour, playing to arenas across Europe.

[11] Pharrell personally offered a support slot to Foxes after hearing her cover of his hit single "Happy" for Radio 1's Live Lounge;[34] Foxes later accused producers of the televised singing competition The X Factor for copying her arrangement of "Happy" for a performance of the song by contestant Lauren Platt, as both versions interpolated the Massive Attack song "Teardrop".

[34] She also collaborated with veteran dance producer Giorgio Moroder on his 2015 solo album, Déjà Vu, featuring on the track "Wildstar".

In the same month, Foxes was announced to be one of the supporting acts of British alternative rock band Coldplay in the European and North American legs of their A Head Full of Dreams Tour, alongside Alessia Cara.

[30] She compiled a playlist to accompany the London Fashion Week premiere of Markus Lupfer's autumn/winter collection in 2014,[13] and later in the year advertised Adidas's Energy Boost line of running shoes.

[69][70][71] For stage outfits on her 2014 tours, Foxes collaborated with fashion brand River Island citing Björk and Patti Smith as inspirations.
