The 67-year-old iconic supermodel is set to tie the knot with her 70-year-old financier beau, she announced in an interview with People on July 15. Johnson -- the first Black woman to appear on the cover of Vogue in 1974 -- noted that she and Maillian have lots of similarities and also shared that their relationship was the first time she had ever dated someone so close to her age. "We know the same songs and we've lived through a lot of the same things," she told the outlet. "As I was breaking boundaries in the fashion industry, he was doing the same on Wall Street. Just finding the love of my life at this point in my life has been amazing." Johnson was married twice before, to real estate agent Billy Potter from 1971-1974 and music producer Danny Sims -- with whom she has a 41-year-old daughter, Anansa -- from 1977-1979.
