Keira Knightley is scared to get married for fear the ceremony won't live up to her dream wedding in romantic comedy Love Actually. The British beauty, whose films have included a string of on-screen love affairs, would prefer to put off the real thing for a while longer. She says, "(Marriage?) Not right now, no. "You know, I've been married five times in films, had three children and countless proposals - and all before I'm 20! "So I think that's quite enough. Plus I don't know how you'd top the wedding I had in Love Actually."
