• Although some of their ties are distant, many well-known celebrities are cousins.
• Nicolas Cage, Sofia Coppola, and Jason Schwartzman are all first cousins linked by their parents.
• Kate Middleton and Ellen DeGeneres, however, have a much more distant relation dating back to the 16th century.

It's no secret that many celebrities have famous parents or siblings, but their high-profile cousins are far less well-known.
