7. Katie Couric and John Molner
Katie Couric got married with John Molner when she was 57 and he was 51. During her wedding speech, she touched on what made a good marriage. "It’s not a lack of love but a lack of friendship that makes unhappy marriages," she said. “But with John, I found a great husband and a perfect friend.”

And it seems like the two are best friends "I feel really lucky because he’s funny and kind and really smart and great company,” she shared with Ellen DeGeneres. “You know, you forget how important it is just to enjoy being with the person.”
