Simpson's time spent with Fightstar reportedly began to cause tensions within the band, amplified when Fightstar announced a 14-date UK tour. Simpson announced to Busted's manager on 24 December 2004 over a phone call that he was leaving the band to focus on Fightstar full-time. On 13 January 2005, Busted's record label announced that a press conference was to be held at the Soho Hotel in London the following day. The next day, the 14th, it was then announced that Busted were splitting up after Simpson's departure weeks before.
