Atomic Kitten are an English pop girl group formed in Liverpool in 1998, consisting of members Liz McClarnon, Natasha Hamilton and Kerry Katona. The group was formed by Orchestral Manoeuvres in the Dark (OMD) frontman Andy McCluskey, who served as a principal songwriter during the band's early years. Sugababes singer Heidi Range was included in the original line-up but was replaced by Hamilton.

The group's debut album Right Now was released in October 2000 and peaked at a disappointing #39 in the UK. After four top ten singles, Katona quit the group and was replaced by former Former Precious singer Jenny Frost. "Whole Again", their next single, became their most successful single when it topped the UK singles chart and became the 13th best-selling single of the 2000s. The group re-released their debut album, with some tracks re-recorded with Frost's vocals which hit #1 in the UK with the album going on to sell over 600,000 copies in the UK.
