13. Matthew McConaughey and Camila Alves
How cute is this? "During Christmastime we go around as a family and everyone gets their turn to open presents," McConaughey said in a past interview. "I had wrapped the engagement ring in about eight different boxes deep so she'd have to keep opening boxes to get to it. And because we go around and swap out and take turns on who's opening presents, she had to get skipped the last 15 times. She kept going, 'Why can't I open that present?' And I said, 'You have to wait til the end.' Finally I get to her and I'm calling my family over ... and her eyes go wide and I take a knee and I said, 'Will you marry me and take my name?'"
