16. Ellen DeGeneres and Portia de Rossi
Leave it to Ellen to propose in a sweet and quirky manner. One day Portia came home from the Arrested Development set with a pet fish, then the rest is pretty much history. De Rossi said in an interview: "We were watching the fish and she said, 'This is a pretty romantic moment, right?' And I said, 'Every moment with you is romantic. And then she gave me the ring".
