"Ex-Girlfriend" is a song by American ska band No Doubt from their fourth studio album, Return of Saturn (2000).
[3] The song features Stefani rapping many of the lyrics rather than singing, and the instrumentals take influence from flamenco (as demonstrated by its guitar riffs), new wave and hip hop.
[9][10] In the United Kingdom, the song became No Doubt's fifth top-40 hit, debuting and peaking at number 23 on the UK Singles Chart and spending three weeks in the top 100.
No Doubt's guitarist Tom Dumont initially played the part of a police officer but was cut from the final version of the "Ex-Girlfriend" video.
