Haim have threatened to leak their album.

The 'Forever' band - sisters Este, Danielle and Alana Haim - are eagerly awaiting the release of 'Days Are Gone' at the end of the month and are so desperate for their fans to hear it, they even thought about posting it on the internet for free.

Este told radio station XFM: ''I threatened to leak it to the powers that be at our label and they weren't very happy about that. I kind of just want it to come out now.

''Everyday I'm like: should I just do it? Should I just do it? Post it on my Facebook?''

Haim were even so caught up in finishing the recording of 'Days Are Gone' they had to turn down the opportunity to appear on the Arctic Monkeys new album 'AM', leaving them disappointed.

Este previously said: ''We tried to push things around to make it work. But when it came down to it, we had to finish our record. We didn't have enough time to come in and learn the harmonies. It would have taken a couple of days. That would have been our biggest dream come true - to sing on an Arctic Monkeys record... It was one of the most painful calls, to say no. Maybe the worst day of my life.''

'Days Are Gone' will be released on September 30.
