As the party winds down, Oprah's staff has a big surprise for her. "The Sydney Harbor Bridge, one of the largest bridges in the world, is going to light up with a big red O on it," Jill says.
While watching a fireworks display, an unsuspecting Oprah is moved to tears when the O appears on the bridge.
Watch the surprise unfold
"You know I don't like surprises, but that was a damn good one. If you're going to be surprised, that is the way to do it," she says. "I know what it took to get that O on the bridge. It took my whole life and everything I've ever done or been or said or tried to be. The fact that the people of that country would think enough of me to put that O on the bridge [is] huge."
