Lindsay Brien

Then: At 5'1," hyperactive" 21-year-old Lindsay is a wild child whose unique personality has served her well as co-host of a radio show in her hometown of Aspen, Colorado. She also created a radio news show for young investors. Now a junior at the University of Michigan, she says her mother and brother might be the only people who know "the real Lindsay" behind the craziness. The loss of her father when Lindsay was a teenager brought her mother, brother and herself even closer together. A southerner from Chesterfield, Virginia, 21-year-old Nathan was raised by his father from the age of five to 15. When his father died of cancer, Nathan moved in with his grandmother and stepped up to adult challenges while still in high school. After a separation of 15 years, Nathan recently was reacquainted with his mother and met his 9-year-old half brother. Like David, Nathan is also a fourth-year student at the Virginia Military Institute. In fact, they lived together in Prague during a semester abroad.

Now: LINDSAY lives in Atlanta and is a morning personality for a popular Atlanta radio station. Before that, she worked as a local television news correspondent in Nebraska, was an intern with a Fox TV affiliate in Detroit, and appeared as a cohost on The View. She is a film graduate of the University of Michigan in Ann Arbor.
