Nadine Coyle has claimed she has always worked separately from the other members of Girls Aloud - right from the beginning of the band.
The 25-year-old singer - about to release her debut solo album while the girl band are 'on a break' - told the Guardian she would always record the initial vocals in the studio without the rest of the band.
Nadine said: "Oh yes. We were very, very separate. We didn't know it any other way.
"From day one. Well, maybe not day one, but definitely week two. And that's how it worked from then onwards. The girls just left me to it. And then they would come in and do their parts, and they would have their holidays."
There have been rumours of a rift between Nadine and the rest of Girls Aloud, but she avoided questions about the band splitting.
Nadine said: "After the last record, it was the right time to go and do our own individual things, and then come back together when the time was right, if the time was right."
But the Irish star, who grew up singing with her father in Ireland, said she was shocked after winning Pop Stars: The Rivals and discovering Girls Aloud were only expected to mime.
She said: "For someone with my upbringing to do another TV show, and hear people saying, 'Oh, just, you know, mime to that...
"I couldn't get my head around it. For it to be that easy. It became more about doing a cute routine that singing a song.
"It took a long time for me to realise, well, this is just what people do."
