The Pussycat Dolls star has admitted she isn’t really close with the sexy group’s main singer and says they only speak because they work together.
She told Britain’s Daily Star newspaper: I get on well with most of the band but not everyone. Look, at the end of the day it’s a job we all have our own lives to lead and our own projects going on.
I think of Nicole as just a business associate not as a friend. You cannot simply group girls together and just expect them to get on, can you? Life doesn’t work like that.
Rumours are rife Nicole is set to leave the band in a bid to concentrate on her solo career but Kimberly insists the Pussycat Dolls could continue without her.
The 27-year-old singer added: If Nicole left tomorrow, we could still carry on. I can see this band going on forever.
It was recently reported Nicole was desperate for Take That star Gary Barlow to write her some songs for her next solo album.
A source said: "Nicole believes that everything Gary puts his hand to is amazing. She is convinced he can provide the hit she needs."
