Like most rock n' roll retirements, Lily Allen's hasn't lasted very long. The singer famously announced her retirement from the music biz in 2009, stating that she had no intention to ever return.

Well, as was probably inevitable, Keith Allen's daughter returned to the stage to join Professor Green at the Stone Roses comeback gig in Heaton Park over the weekend. The duo performed their 2010 hit 'Just Good To Be Green'.

Allen was spotted last month at a recording studio in London, fuelling rumours that she is working on album #3.
