The 39-year-old singer says she doesn't want to bring in a star who she will pretend is her friend as some talent show judges do. Instead she plans on asking her longtime friend to accompany her at the judges' houses stage, reported Sun online.
"Whoever I bring in as my guest helper will be authentic to me. It wouldn't be rent-a-celeb. I'd possibly ask George as that feels authentic. It would either be him or my mum," Halliwell said.
The singer also said that she wished the talent show had been around when she was trying to carve out a career.
"My mum was a cleaner, we didn't have money for stage school, so I'd have entered the X Factor. I love it for that reason," she added.
