Following the premiere of their new single Something New earlier this week, Girls Aloud have confirmed details of a tour next year and the release of a new greatest hits album Ten on November 26.
The 18-track retrospective will feature four new songs - On The Metro, Beautiful 'Cause You Love Me, Every Now And Then and Something New, which will be released as this year's Children In Need single on November 18.
The girls confirmed they will be performing Something New live for the first time during the Children In Need fundraiser TV show on November 16.
Cheryl, Sarah, Nadine, Nicola and Kimberley will hit the road next Spring for a string of dates, with tickets going on general sale at 9am on October 26.
Speaking at a press conference at London's Corinthia Hotel today (19 October) about their decision to reunite, Kimberley said: "It felt like the right time. It feels comfortable to be back together - like a comfort blanket."
Cheryl added: "Touring is the best thing about what we do. And to get to say thank you to the fans is just amazing."
