In a 1976 interview with People, Natalie Wood reminisced about the first time she saw Robert Wagner when she was 10 and he was 18. "I turned to my mother and said, 'I'm going to marry him.'" Their paths officially crossed in 1956 when 20th Century Fox set them up for a publicity date. In the very next year, Wagner proposed to Wood in a rather traditional way by dropping a diamond ring engraved with the words "marry me" into her champagne glass.

The stars tied the knot soon after on December 28, 1957, but abruptly divorced after nearly five years of marriage. Many speculated that the marriage ended because Wood caught Wagner cheating on her with another man. Even Wood's sister Lana seemed to confirm these allegations, according to News.com.au. But that wasn't the end for the high-profile pair. The couple remarried in 1972, a decade after the divorce. 

In the book, "Natalie Wood: Reflections on a Legendary Life," an unreleased essay written by the star possibly shared some insights into the reconciliation, according to People. "If you love someone and make a commitment to them, the love does not vanish because you have signed a legal document called a divorce paper," she penned. "The failure of all your hopes, promises and dreams gives you one more thing in common — mutual sadness."
