13. Lady Gaga
Lady Gaga’s talents stretch far beyond her singing-songwriting abilities, as she is not only a musician but also an actress, dancer, and fashion-designer. She has several awards under belt, including an Oscar and 9 Grammys. Only recently did she reveal her struggle with fibromyalgia, a disease that causes pain all over the body. Like others who suffer from the disorder, Gaga experiences extreme fatigue, increased sensitivity to pain, and muscle stiffness. Still, being the fabulous performer she is, she pushes through the pain.
