The 'Call The Shots' stars are said to have ended on a sour note following news of their break-up last week.
Girls Aloud are apparently upset with Nadine Coyle after the singer posted a Twitter message about how she didn't want the band to split up last week.
The group announced they were separating after ten years together following their final 'Ten' tour date in Liverpool last week – and are now reportedly on "terrible terms" due to Nadine's message on her social networking account.
"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," a source told the Daily Mirror.
Sarah Harding was apparently one of the most angry with the tweet and didn't hesitate in letting her bandmate know how she felt.
"As soon as Sarah saw the tweet she called Nadine to say how angry she was," the insider added. "The tweet made it look like the girls went behind Nadine's back to make the decision."
They continued: "But 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."
Meanwhile, Cheryl is apparently ready to take a six-month break from the limelight following the split and may take some time to go travelling around the world.
