The 33-year-old model-and-actress says the 'I'm A Virgin' hitmaker was her idol growing up and she always wanted to dress like her, reported The Daily Telegraph.
"I would buy tonnes of hairspray. I had a bad perm and would scrunch my hair. I'd go through a can of hairspray a week," Brook said.
Although she was fascinated by Madonna, Brook insists her biggest role model when it came to hair and beauty was her grandmother.
"My earliest beauty memory was at my grandmother's house. She was always into beauty products and I remember her teaching me how to cleanse my face using cleansing milk. Nowadays, my ethos is to take good care of my skin - but I also think that if you have a clear and happy mind, that shines through and makes you beautiful.
