18 Celebrity Couples Where Only One Person is Famous

17. Mary-Kate Olsen and Olivier Sarkozy

For this relationship it’s not just that Olivier Sarkozy is not famous, but also that he is much older than Mary-Kate and he looks it. Whether it is the fact that he is French or that there is something more to it, this couple has been together since 2012 and are now engaged. Maybe 17 years is not that big of an age difference after all.
