20. Shania Twain
The singer has opened up about growing up in an abusive household and almost thinking her mum was dead one time:
“I really thought she was drowned, or dead, or that he had just smashed her head in and she was never going to wake up. … She looked dead. She was unconscious, she was limp, hanging from his, you know, her, he had her hair in his hands.”
She also says her parents were burdened due to having five kids and their arguments stemmed from their financial struggles – Shania often went to school hungry because there wasn’t enough money for groceries or rent.
