Girls Aloud have spoken of their delight at being back together and confirmed plans for another tour and a greatest hits album, including four new songs.
Cheryl Cole said: "We were all getting dressed this morning and it actually feels really normal." Kimberley Walsh added: "It feels so comfortable to be together, like a comfort blanket in a really nice way."
The girls lined up to face the press for their big announcment
Cheryl and Kimberley sat alongside Nadine Coyle, Sarah Harding and Nicola Roberts at a press conference at the Corinthia Hotel in London.
Asked if they will bring out another album full of new songs, Nadine replied: "We'll have to wait and see how the fans react."
And they added that they have already released 10 new tracks since their last greatest hits album.

The girls will perform 'Something New', their first single since 2009's 'Untouchable' which leaked on Tuesday, on Children In Need (16 November) and complete a UK tour including London's O2 Arena on 1 and 2 March.
Girls Aloud are celebrating a decade at the top of the pop game, when asked which moment has been the biggest highlight over the past 10 years, Kimberley said: "When we won the Brit award that was a really amazing night for all of us."
The girls tweeted a picture of them having a "last minute huddle" before the conference.
It was also announced today that Girls Aloud have become the biggest selling girl group of the 21st century, based on single sales.
They have racked up sales of nearly 4.3m singles since their 2002 debut 'Sound Of The Underground', which sold over 653,000 copies in the UK. The track is also their fastest selling single, shifting 213,000 copies in its first week.
Over the last decade, Girls Aloud have had 20 top ten singles and four Number Ones, according to the Official Charts Company.
