Cheryl Cole unsure of Girls Aloud future

Cheryl Cole has refused to commit to a long-term future with Girls Aloud.

The pop singer revealed that she is looking forward to settling down and having children with her footballer husband Ashley, and admitted that this would be more fulfilling than concentrating on her career.

"We live in a pop industry bubble and see it for what it is. We're well aware that at any moment in time the bubble can burst," Cheryl told the Daily Mail. "If this all ended, I would like to be a mother, have children.

"Babies are definitely something I'm looking forward to - and something I want to do sooner, rather than later. That's going to be the highlight of my life - having children and settling down. But every decision you make as an individual affects four other people's lives. This is the debate at the moment."

Cole added that the group's future may depend on the success of their new album Tangled Up and next year's tour.

"We'll see how this album goes then sit down and have a conversation about the next stage," she explained. "All we can say for definite is that we'll be together up to the end of the tour."
