Siobhán Donaghy is one of the three original members of Sugababes (with Keisha Buchanan and Mutya Buena). Born Eastcote, Hillingdon, London 1984. In 2001 she left the band to pursue a solo career. While signed to London Records she wrote her début solo album Revolution in Me with Cameron and Marlon McVey, which was released in September 2003. The first single from the album was Overrated which made its way into the UK top 20. However, the second single, Twist of Fate, barely reached the UK top 75. Due the lack of proper promotion, and the failure of the second single, the album 'Revolution In Me' only reached #117 on the UK album chart.

After the album’s lack of success Siobhán left the label and was left without a recording contract. After an extended holiday she started to work on her second album alone. She subsequently signed with Parlophone, part of the EMI group. Parlophone released Don’t Give It Up as the first official single on April 16, 2007 which debuted at #45 in the UK chart. Siobhan’s second album, Ghosts, was released in June 2007, peaking at #92 on the UK albums chart.

Siobhan has collaborated with the likes of Morcheeba, James Sanger, Siobhan Fahey (ex-Bananarama and ex-Shakespear’s Sister). In October 2007, she had her London theater debut, appearing as Mimi in Rent.
