O'Meara was given a full scholarship to attend the Italia Conti Academy of Theatre Arts, where she excelled in music, acting and dance – receiving a standing ovation by the heads and principals for her rendition of the song "Summertime".

[5] At age 16, O'Meara joined the earliest incarnation of girl group Solid HarmoniE and flew out to Sweden to work with record producer Max Martin.

She'd move to Essex and performed open mic nights until she was spotted by the S Club 7 team in a country and western bar.

[6] The show, which was a children's sitcom, often mirrored real life events which had occurred in S Club, including the relationship of Hannah Spearritt and Paul Cattermole, as well as the latter's eventual departure from the group.

S Club's second last single reached number-five in the UK charts and their final studio album failed to make the top ten.

[7] In 2004, O'Meara signed with Simon Fuller as her artist manager and began recording her debut solo album, planned to be released between September and December.

[8][9] In July 2005, O'Meara signed with Sanctuary Records and on 26 September was released her debut solo single, "What Hurts the Most", a version of Mark Wills's 2003 song.

[14] In November 2008, O'Meara, Bradley McIntosh, and Paul Cattermole formed the spin-off group S Club 3 and had been performing in nightclubs, universities and Butlins holiday camps around the United Kingdom.

A 20-year-old man was arrested and it was suggested the attack was linked to her Celebrity Big Brother appearance where she was accused of racially aggravated bullying.

[16][3] O'Meara featured in a cover of the Python Lee Jackson song "In a Broken Dream" on the Popes' 2012 album New Church, her first released recording in seven years.

[22][23] In September 2022, O'Meara joined the Celebs to mark the 40th anniversary of the Michael Jackson classic album Thriller and raise money for Great Ormond Street Hospital, with a new rendition of the title track, which was released on the independent record label Saga Entertainment and produced by Grahame and Jack Corbyn.
