The former manager of Girls Aloud, Louis Walsh, has said that the members of the group did not get along. He said of the recently retired group that they pretended to get on well in public.
Speaking to the Daily Star Sunday, the X Factor judge said "I didn't enjoy working with Nadine, Kimberley, Nicola, Sarah or Cheryl either."
"They didn't get along with each other and hated me. I found their rivalry difficult to cope with. It's hard to get them to get on well.
"They all pretend to get on well in public, but underneath, all they want is to be the skinniest and go out with the most famous footballer and be in the middle of pictures and all that."
Walsh managed the group when they were formed as part of the television show, Popstars: The Rivals in 2002.
Cole later claimed that his involvement with them as a group was minimal.
