Kate Nash grew up in Harrow, London. Her first interest in music came when she learnt how to play the piano. Kate attended St. John Fisher school and St. Joan of Arc School before studying at the BRIT School for Performing Arts and Technology. Kate initially wanted to act but after rejection and a broken foot she found comfort in song writing.
After various live performances Kate uploaded her music to Myspace and she received support not only from users of the site but from Lily Allen also. Kate found a manager and signed with Fiction Records.
