Updated: Nadine Coyle denies calling Cheryl Cole 'a failure'

Nadine Coyle has denied reports that she was overheard calling her Girls Aloud bandmate Cheryl Cole "a failure".

According to Heat, the 'Insatiable' singer had made the comments while out for pre-birthday drinks in a New York bar last week.

Coyle was alleged to have said: "I have more talent in my little finger. Why would I be jealous of a failure?

"Cheryl got way too big for her boots. She thought she could walk on water and had to learn the hard way that things don't always work out as planned. People don't know the real Cheryl like I do."

The source added: "Nadine was being quite hard and really letting rip about her feelings. As the conversation turned towards Cheryl's recent sacking, Nadine said it was for the best and that Cheryl would have been 'out of her depth on the US X Factor'."

A supposed friend of Coyle's claimed: "When Cheryl got the US X Factor job, Nadine couldn't understand why. Even when Cheryl got the UK X Factor job, Nadine thought it was ironic, as she had always felt she was the 'best singer in the band'.

"Nadine feels it's her time. She has said she'll be 'bigger than Cheryl could ever dream of being'. And she isn't going to let anyone stand in her way."

However, responding to the allegations on Twitter, Coyle wrote: "Not true. Stop using me as the scape goat for lack of stories."

Cole's PR firm also doubted the truth of the story, quipping on Twitter: "Well now Cheryl has no friends that should mean no more stories from 'pals' in press."

Coyle and Cole are rumoured to be planning a reunion with Nicola Roberts, Sarah Harding and Kimberley Walsh for a 2012 Girls Aloud comeback.
