Prince William and Kate Middeton went out for eight years before getting engaged.

What does a moon being in Cancer even mean?
"On the day you're born," Miller explained, "the moon - the moon moves very quickly, you know; it only stays in a sign for about two days. So, for both of them to have the moon in the same place, that's pretty extraordinary."
Miller wasn't as crazy about the date for the wedding - April 29.
