Following disappointing sales, the group were dropped and later signed with Virgin, released a final studio album X on 10 October 2005 and disbanded in 2007.

[2] While the five winning contestants of Popstars formed Hear'Say, the five runner-up contestants—Michelle Heaton, Tony Lundon, Kevin Simm, Jessica Taylor and Kelli Young—formed the group Liberty.

[3] Shortly after forming, Liberty received a legal challenge in the UK High Court from a funk R&B band, also called "Liberty", who achieved success in the 1990s, including being awarded Capital Radio Band of the Year, playing Wembley Arena, European tours and the release of albums in the US, Europe and UK.

The final judgment was in favour of the funk R&B band and the ex-Popstars then asked readers of UK tabloid newspaper The Sun to suggest a new name.

Following a short break, the group released "Being Nobody", a mash-up of Chaka Khan's "Ain't Nobody" and The Human League's "Being Boiled".

The music video featured the group walking along disused railway lines, for which they were criticised by safety organisations.

Kevin Simm appeared on Channel 4's The Games, competing in a series of sporting events (in which he placed second overall, behind Philip Olivier).

Tony Lundon and Kelli Young took the time to work on new tracks for the band's third album, whilst producing and writing for other artists.

During this period, The Sun newspaper reported that the group were to re-release Being Somebody with a cover of the 1990 hit "Back to Life", but this never materialised.

It was released in September 2005 and was well-received, achieving a large amount of television and radio airplay; it entered the UK charts at number five to become their first top ten hit in two years.

In late October, the group announced they had been asked to record the official 2005 Children in Need single, so they teamed up with producer Rod Gammons to record two tracks for double A-side release: "A Night to Remember" (a cover of the Shalamar song) and "Everybody Dance" (a (Chic cover).

Students were told the band were not returning to finish their set, met by jeers from the crowd, who had paid £37 each for the evening.

Michelle Heaton wrote on the group's official site that they would be releasing a new single in the new year (2007), a song from a forthcoming film, but this did not happen.

[12] On 18 October 2012, it was announced that Liberty X, along with five other pop groups of their time – B*Witched, Honeyz, 911, Five and Atomic Kitten – would reunite for an ITV2 series called The Big Reunion, in which they would reveal about their individual stories about their life in the band before reforming for a gig at the Hammersmith Apollo, singing their greatest hits.

[13][14][15] The show, which aired from 31 January to 28 March 2013, followed the groups rehearsing for two weeks ahead of one major comeback performance at the London Hammersmith Apollo on 26 February.

[17] On 11 February, it was confirmed that due to high demands for tickets and the popularity of the show, an arena tour around the UK would be taking place from 3–12 May 2013.

[19] On 29 March 2013, Heaton confirmed that Liberty X would yet again disband following the concerts, saying: "We talked about it, and we thought we've got so many children between us and quite a few things individually going on that we didn't want the pressure to be successful again.

[23][24][25][26][27][28] In 2017, Heaton, Taylor and Young reformed Liberty X as a three-piece girl group[29] and have continued touring at music festivals and Pride events since.
