Girls Aloud formed on Popstars: The Rivals in 2002

All 5 members of Girls Aloud attended a top-secret meeting in London last week to discuss the details of their 2013 comeback.

Cheryl Cole, 28, Kimberley Walsh, 30, Sarah Harding, 30, Nicola Roberts, 26, and Nadine Coyle, 26, are hoping to embark on an arena tour and release new material to mark the 10th anniversary of their formation on Popstars: The Rivals

'They were really excited to see each other - even though Cheryl, Nicola and Kimberley meet up regularly,' says a source.

'They haven't seen much of Sarah recently following her stint in rehab
and Nadine has been out of the picture since living in LA.'

After Girls Aloud's last performance together in 2009, where they supported Jay-Z and Coldplay, the girls have pursued their own careers.

Nadine has been keeping a low profile in the US since releasing her debut album Insatiable in 2010.

'Nadine was eager to speak to the girls face-to-face,' the source tells The Sun, 'to ensure there is no bad blood.'
