CLOSING IN: Aw. "The O.C." lovebirds Rachel Bilson, 22, and Adam Brody, 24, are moving closer together -- literally. Brody just bought a home in the Hollywood Hills to be near Bilson, who has lived in a family-owned condo in the area for years. But Bilson thinks that's still too far away and is upgrading to a $1.6 million place just down the street from Brody, according to the New York Post. Good grief! Why don't they just shack up together, pay the movers once and get it over with?
