'Insatiable' songstress Nadine Coyle has admitted that although the members of Girls Aloud have grown up considerably since their hiatus, things still 'kick off' if they have a disagreement about something.

During an interview with Gaydar Radio, the Irish hitmaker explained that the girls have all matured but they still bicker occasionally:

"Sometimes it can all kick off. Then someone might back the other one up and be like "no, she's right because of this!" And then it all starts."

Despite their infrequent differences, Coyle added that the dynamic between them is fantastic because they're all committed to the Girls Aloud reunion and are excited about the future:

"Everybody has [grown up]. We've been very fortunate. I just think it's very good that everyone is in a good frame of mind to come back and do all the stuff again."
