Madonna

Madonna, 64, confessed to Harper’s Bazaar that, long before she was famous, she rebelled by refusing to shave her armpits.

The 'Vogue' hitmaker recalled in 2013: "I saw how popular girls had to behave to get the boys. I knew I couldn't fit into that. So I decided to do the opposite. I refused to wear makeup, to have a hairstyle. I refused to shave. I had hairy armpits."
