"Da Ya Think I'm Sexy?", also written "Da' Ya' Think I'm Sexy", is a song by British singer Rod Stewart from his ninth studio album, Blondes Have More Fun (1978). It was written by Stewart, Carmine Appice and Duane Hitchings,[4] though it incorporates the melody from the song "Taj Mahal" by Jorge Ben Jor and the string arrangement from the song "(If You Want My Love) Put Something Down On It" by Bobby Womack.[5] The song was released as the first single from Blondes Have More Fun in November 1978. It spent one week atop the UK Singles Chart in December 1978 and four weeks atop the US Billboard Hot 100 in February 1979. Billboard ranked it number four on its Top Singles of 1979 year-end chart.[6] It also topped the charts in Canada for four weeks and in Australia for two weeks. Royalties from the song were donated to the United Nations Children's Fund (UNICEF) and Stewart performed the song at the Music for UNICEF Concert at the United Nations General Assembly in January 1979.[7] Rolling Stone ranked the song at number 308 in its 2004 list of the 500 Greatest Songs of All Time.[8]
