The Spice Girls singer joked that she and 6-year-old Bluebell Madonna are like characters from Absolutely Fabulous.
"With my daughter, it's like Ab Fab - she's the sensible one. She tells me to stop skipping down the street. She says, 'Mummy, stop it. You're embarrassing me'," Halliwell told Hello magazine.
''I know everyone is proud of their child, but she really is lovely and I'm blessed. It's like growing a plant - when it starts to flower you're like, 'Wow! I helped to cultivate that personality'.
''I try to allow her to be who she is rather than impose what I think she should be.''
Xtra Factor host Caroline Flack recently named Halliwell as one of her favourite X Factor guest judges because she was "mental".
Upon arrival at the Liverpool auditions, Halliwell climbed out of her car window and used a megaphone from the vehicle's roof.
