Florence Ellen Arnold (born 28 December 1988), better known as Florrie, is an English pop singer-songwriter, drummer and model. Closely associated with the Xenomania production house, since joining as their in-house drummer in 2008 she has played live and on record for popular artists such as Kylie Minogue, Girls Aloud and the Pet Shop Boys.

In 2010, she began a solo career. She has drawn positive reaction from the online music community for releasing her own material in collaboration with remixers such as Fred Falke for download without charge. In 2010, Florrie released a four-track EP titled Introduction, followed by the six-track EP Experiments in 2011, and by the four-track EP Late in 2012. In 2013, Florrie released a single, "Live a Little", that was used in promotion for Sony's XBA-C10 in-ear headphones campaign. In 2014, she announced that she had signed to a major label, Sony Music, and released an EP, Sirens. She would eventually depart with the major record label, and comeback as an independent artist on 2019 with the release of "Borderline", which would be later included on her first compilation project titled Personal, released on 2023.

Florrie released her debut album, The Lost Ones, on 14 June 2024.

Florrie was born Florence Arnold on 28 December 1988 in Bristol, where she attended Colston's Girls' School. She left school at 17. She became interested in playing the drums when she was in Greece on a family holiday at age six. As a teenager she started her own band called Fi Fi Saloon, which performed Avril Lavigne covers and original songs she described as "really trash, punky girl rock-pop". She moved to London when she was 17 years old and gigged with several bands including Selfservice, who signed a development deal with songwriter Guy Chambers. Florrie performed with Selfservice at night and worked part-time as a nanny during the day.

A meeting with the manager of Australian singer Gabriella Cilmi led Florrie to a successful audition as the drummer in the houseband of Xenomania, the successful Kent-based production team. Prior to joining Xenomania, she worked at GAP and quit as soon as she was offered a job as a professional drummer. Her first job was playing on Girls Aloud's 2008 single "The Promise", although she also assisted with administration work. She provided drums and drum programming on Xenomania-produced tracks by Alesha Dixon, Rebecca Ferguson, Kylie Minogue, Pet Shop Boys, and The Saturdays. She also co-wrote the 2010 single "One Touch" for the short-lived female duo Mini Viva, "Something New" (2012) for Girls Aloud, and "What Are You Waiting For?" (2014) for The Saturdays. Xenomania producer Brian Higgins encouraged Florrie to sing one of the songs she had written, which prompted her to pursue her own music career.

Florrie's debut release, a Fred Falke remix of "Call 911", reportedly had over 1,000 downloads around the world within a few days of its February 2010 release. In mid-2010, Florrie was announced as the face of the then-new Nina Ricci fragrance Nina L'Elixir. She starred in the TV advert for the campaign performing a cover of Blondie's "Sunday Girl", and also featured in print advertisements shot by Ruvén Afanador. In July 2010, Florrie featured on The Guardian's "New Band of the Day" column. Besides these two tracks, three more were released as remix-only versions: "Panic Attack" (April 2010), "Fascinate Me" and "Come Back to Mine" (May 2010).

Florrie released her debut EP, Introduction, in November 2010 through the iTunes Store. The EP was made available for free download on her official website, as well as on 12" vinyl pressings limited to 500 copies. Music blogs Popjustice, ArjanWrites.com, electronic rumors, Dödselectro and Sundtrak praised the quality of the music, while noting the free availability of the tracks and expressing interest for future material. Others identified how the awareness of Florrie's music has been assisted by online social networks and a grassroots strategy. Florrie told Ponystep magazine:

I think it's really important to have that contact with fans and for them to be able to buy into your world or you as a person without any pressure from a corporation  ... It's a better way of doing it because people can feel like they discovered you as opposed to a major label. I want my fans to feel like they have some sort of ownership.
