Girls Aloud could reunite without Nadine Coyle
'It's been a painful decision, but they've decided that the future of Girls Aloud lies without Nadine,' a source tells The Sun.
'They've all been on a roller-coaster ride since 2002, and have just grown apart from Nadine.
'Disputes began cropping up towards the final days of the band before they went on a hiatus.
'The four remaining girls want to return on their own terms.'
Earlier this year Nicola admitted that the band hadn't spoken to Nadine in months.
Nadine, 25, is currently based in LA working on solo material and only found out about Cheryl's malaria infection via Twitter.
