Coyle 'frustrates' Girls Aloud bandmates

Nadine Coyle has reportedly 'frustrated' the rest of Girls Aloud because she is delaying the group's reunion.

The singer, who is currently working on her debut album in LA has yet to set a release date for her solo effort, which was originally scheduled for February.

A source told the Daily Mirror: "The girls are getting frustrated waiting around to see what she is planning to do.

"Nadine has been working so long on this album that it's strange there isn't even a date pencilled in for its release. They'd originally scheduled it for early 2010. But there is no finished product as yet and she is still writing.

"If Nadine's album isn't released by the end of this year, she will only be able to tour by the end of next year, which is when the others were hoping to bring out another Girls Aloud album. Everything is in limbo at the moment."

They added: "There is no way Nadine is going to leave the band - despite the ill feeling... it wouldn't be in her interests to quit."

Bandmate Kimberley Walsh recently stated there was no conflict in the group, but described herself growing apart from Coyle as "inevitable".
