Christie Brinkley offers a revealing glimpse into the challenges of being one of the world’s original supermodels in her new memoir, “Uptown Girl.”

Christie Brinkley says 'booze was the other woman' in her marriage to Billy Joel: 'He preferred to be with 'her' rather than with me.'

In a new memoir, the supermodel goes into pretty excruciating detail about the rocker’s wildly excessive drinking, frightening behavior and angry denials when confronted about cheating.
