We've known that the pretty pair was not only onscreen lovers, but now they took their teen relationship to another level. They got engaged. Brody and Bilson play teenagers Seth Cohen and Summer Roberts in the hit American TV show, which follows the tangled love lives of rich youngsters living in Orange County, California. The young stars are looking for a house together in Los Angeles. A source at US television network Fox says, "They are both so much in love and want to settle down together." "Adam went down on bended knee in a very traditional way and they plan to get married in the new year. It's the talk of the set, but they have been trying to keep it quiet." Why keep it quiet? Enjoy every minute, Rachel and Adam! Congratulations!
