Tiger Woods mistress Jamiee Grubbs once made the mistake of commenting that the golfer’s calves were very thin. The golfer, she told Us, did not take this well: “I remember him giving me the biggest death look. He told me he was very insecure about the size of his calves. He said, ‘I can’t grow calves.’ And I was like, ‘Okay, sorry!’” [Us]
