Tiger Woods
Woods became the face of golf after a rapid rise that saw him emerge as one of the greatest of all time. He enjoyed incredible success on the PGA Tour and attracted massive endorsements. Nike, Gillette, and EA Sports made deals with the legendary player. But it all came crashing down because of his wild drug use and sex addiction.

In 2010, a drunken Woods crashed his vehicle outside his Florida home. Then many women emerged and claimed that they had intimate relations with the superstar. These included porn actresses and strippers and it became a massive scandal. In the end, Woods’ wife left him and he went to rehab for sex addiction (via The Guardian).
