Billy Crystal and Janice Crystal – 50 years
Another long-standing celebrity marriage is Billy and Janice Crystal’s. Billy Crystal gained recognition for his leading role in the movie When Harry Met Sally. But he met Janice long before that when he was only 18 years old. Now, the couple has been together for nearly 50 years, an impressive milestone.

According to the couple, laughing together is a big part of a happy marriage (it sounds like a cliché, but it works). In addition, “we’ve grown together, we’ve parented together, we’ve grand-parented together,” Billy Crystal explains. It looks like sharing experiences and listening to your significant other leads to great success in relationships!
