Lowe was born in Westminster, London, England. She grew up in Primrose Hill, north London, and stayed with grandparents to continue her education at South Hampstead High School when her mother, Pearl Lowe, moved to Hampshire. Lowe has two younger half-brothers and a half-sister from her mother's marriage to Danny Goffey; Alfie, Frankie and Betty. She also has three younger half-brothers from her father's marriage to Gwen Stefani; Kingston, Zuma and Apollo. Until 2004, Lowe was believed to be the daughter of Pearl Lowe's ex-lover Bronner Handwerger, but a paternity test revealed that her godfather, Bush singer/guitarist Gavin Rossdale, was, in fact, her biological father. Her mother Pearl Lowe wrote about the situation in her book, All That Glitters. Daisy's paternity was not questioned early on, and Pearl listed "Bronner Lowe" on Daisy's birth certificate without informing Lowe that he may not be the father. At age 14, Daisy found out neither Bronner nor her mother shared her O-type blood. She mistakenly thought that one parent must share her blood type and that Bronner could not be her father (based on a common misunderstanding of blood type inheritance). Daisy confronted her mother, who admitted to a one-night stand with Rossdale. Daisy and Pearl's lawyers arranged a paternity test, which Rossdale at first refused. Results confirmed Rossdale was her biological father.
