It was Hollywood beauty Keira Knightley’s mother who advised her to pierce her navel, so she could feel “cool” in school. The stunning “Bend It Like Beckham” star had been experiencing “difficulties” at school when her playwright mother Sharman Macdonald encouraged her to get a stomach ring to boost her confidence, reported “It was actually my mum who made me do it. I was having a hard time at school. I don’t really remember why. She decided I needed a little secret so I would think I was cool, then she took me to a piercing parlour,” Knightley was quoted as saying. — HNS
