The Civil Wars star Joy Williams has denied fan suggestions she has reconciled with her bandmate John Paul White following the cancellation of their 2012 tour, revealing the pair are no longer on speaking terms.

The folk duo scrapped all live shows in November (12) due to "internal discord" and "irreconcilable differences of ambition", but the stars were thought to have settled their differences in December (12), amid reports they had reunited in the studio to record new music.

Now Williams has opened up about the status of their hiatus, confessing the future of the group remains uncertain, even as the August (13) release date of a new album quickly approaches.

She tells the Associated Press, "John Paul and I aren't speaking right now but, to me, that doesn't determine the outcome of the band, because if we're not speaking we can't determine the outcome of the band at this moment. So the other elephant in the room is what's happening with the band? The reality is I'm not even quite sure."

Stopping just short of detailing their troubles, the 30 year old admits the two had problems before setting out on tour and she's convinced fans will be able to pick up on the tension in their songs, which were written last summer (12).

She adds, "If you want to know what happened to the band, listen to the album... (It) chronicles loss and regret and anger and victory and sweetness and loyalty and I hope that people get the chance to listen to it... It's so honest and it's so rich and, not to toot my own horn, I'm just really proud of what we created together. And we created it together - we just happened to be in a bit of a civil war ourselves."
