Girls Aloud have parted on "terrible" terms.
The 'Something New' hitmakers are allegedly furious former bandmate Nadine Coyle shared her sadness about their recent split over Twitter because she made it look like it wasn't a mutual decision.
A source told The Mirror newspaper: "They have parted on terrible terms. The girls hadn't seen much of US-based Nadine until they reunited for the tour and now it doesn't look like they'll ever see much of her once she's gone back to LA.
"As soon as Sarah [Harding] saw the tweet she called Nadine to say how angry she was. The tweet made it look like the girls went behind Nadine's back to make the decision."
The band - who were formed on 'Popstars: The Rivals' in 2002 - announced on Wednesday they were to go their separate ways following their successful 'Ten - The Hits' reunion tour.
However, Nadine quickly took to Twitter to claim she "couldn't stop" them and wanted to "keep going", leaving the other girls - Sarah, Cheryl Cole, Kimberley Walsh and Nicola Roberts - at war with her over her behaviour.
You should know by now I had no part in any of this split business. I couldn't stop them. I had the best time & want to keep going. Xxxx— Nadine Coyle (@NadineCoyleNow) March 21, 2013
The insider added: "The plan had always been to split after the tour. Nadine also felt the sharp end of Cheryl's tongue. Nadine's behaviour has left a bitter taste in everyone's mouth."
