Nadine Coyle is blaming "busy schedules" for not hearing from her fellow Girls Aloud band mates Cheryl Cole, Sarah Harding and Kimberley Walsh.

The singer, whose first solo single Insatiable is going to be out next month, says none of the girls have been in touch with her to wish her good luck for her solo career, except for Nicola Roberts.

Coyle said: "I was talking to Nicola. She said 'congratulations,' and 'that's lovely'.

"It was really nice to hear from her. But I think everybody has been so busy."

Nadine now lives in the US with her fiance, American football star Jason Bell. Rumours of a rift between some bandmembers have been circulating for a while.

Earlier this year, Nicola Roberts revealed in an interview that none of the other girls have heard from the Irish beauty in months, but denied any feud in the group.
