Niki Taylor is a bonafide supermodel. She signed her first modeling contract at 13 and began walking runways in Paris soon after. At 15, she landed her first Vogue cover -- the youngest cover girl in the magazine's history. By age 16, she had earned her first million.
But Taylor's life is far from picture perfect. In 1995, she suffered the first of two life-altering tragedies when her sister Krissy died unexpectedly from a rare, undiagnosed heart condition at age 17.
