Some girls spend their entire lives planning out their wedding. They know what kind of dress they're going to wear, the theme of the wedding, and who will serve as a maid of honor. Keira Knightley is not one of those girls. In fact, she has no plans for marriage at all.
She tells People magazine, "Marriage is a big thing for a lot of women, but not me. I don't have plans. You never know what's going to happen day-to-day, so you might as well just deal with it as it happens."
There's always the Brangelina route. They've actually managed to outlast a lot of marriages in Hollywood.
