Members: Tina Peacock

Supersister were a short-lived British girl pop band made up of Eleanor Phillips, Louise Fudge, and Tina Peacock. They supported Steps and Hear’Say on tour in 2001. Eleanor's brother, Sean Phillips (3), was the group's "unofficial" fourth member and wrote/co-wrote many of Supersister's songs.

Supersister released only three singles but an album was in works. The album was never released due to Gut Records bankruptcy in 2008.
Brian Dowling from Big Brother made Supersister's song "Coffee" well known and was performed at G-A-Y in 2002.
