Nadine Coyle feels cut off from the rest of Girls Aloud.
The sexy singer is based in Los Angeles while the rest of the group - Cheryl Cole, Sarah Harding, Kimberley Walsh and Nicola Roberts - are in London and friends say relations between her and her bandmates are "strained".
A source said: "I think the main problem is that Nadine lives in Los Angeles and the rest of the girls all live in the UK.
"The girls are all really busy but they meet up in London when they can and chat on the phone all the time.
"Unfortunately because Nadine isn't around she must feel like she's being left out. It's not intentional but I think Nadine must be feeling a bit frozen out.
"I don't think there has been much contact between Nadine and the others since they went their separate ways at the start of the summer so I wouldn't be surprised if things feel a bit awkward and strained when they meet up."
Girls Aloud are supporting Coldplay at Wembley Stadium this weekend and Nadine is said to be considering her future with the group after the shows.
The source added to Northern Ireland's Belfast Telegraph: "I think it's difficult for Nadine - she must feel very torn. She's trying to juggle two lives - one in Los Angeles with her family and boyfriend and one in London with Girls Aloud.
"I've heard she's been thinking very seriously about her future. I'm sure she's hoping that once she's back in London she will be fine and the concerts will give her a chance to bond with the girls again."
