Cheryl Cole wanted to become a "big sister" to Britney Spears
The `Fight For this Love` singer thought she could help Britney - who suffered a public meltdown, culminating with her shaving her head in 2007 - become "normal" again, according to her ex-minder Craig Balkam.
A friend told how Craig had said: "She used to talk about BritneySpears. She kept saying she wanted to help Britney - that she thought she could become like a big sister to her and make her normal again after all her crazy behaviour."
Cheryl, 28, was not as big a fan of eccentric star Lady Gaga, however, because of her provocative stage antics.
The source added to the Sunday Mirror newspaper: "She had a thing about Lady Gaga too. She loves Lady Gaga`s music but disapproved of her stage show. She`s quite shy and not that comfortable with overly sexual behaviour. She`s very proper and ladylike."
Cheryl`s had attempted to establish herself as a star in the US, but it backfired when she was sacked from the judging panel of talent show `The X Factor` after only four days of filming earlier this year. She has since returned to the UK, where she has kept a low profile and reportedly reunited with her ex-husband, Ashley Cole.
Cheryl had confided in Craig that she had long felt like a "prisoner" and longed to turn her back on life in the public eye.
The source added: "Cheryl kept saying she wanted to get out of showbusiness. She said she had enough of being a prisoner in her hotel room - that was a phrase she used a lot.
"She said wanted to be a normal person again. But at the same time she was very keen to crack it in America - as though she was torn between the two."
