Millie, 29, works as an Environmental Teacher at the Tennessee Aquarium and describes herself as a motivated, fun, daredevil/adventurer with no fears, except for mayonnaise: she hates the stuff. She holds a BA in Communication Arts from Bryan College in Dayton, Tennessee, and his lived in Taiwan, teaching English, and traveled to Israel and Russia. Speaks French, conversational Chinese and some Russian. Millie was once on the Tonight Show after Leno bumped into her and her roommate and asked them to "say stupid Baywatch lines in our shower--in bikinis--which we did," so she has a wild side somewhere deep down. She enjoys volleyball, water skiing, rollerblading, snorkeling and swimming, and blows off steam by running, talking (or fighting) with Chuck, praying, and reading the Bible. Millie believes her man Chuck is "hotter than Brad Pitt." On the downside, her man can also be too "anal and meticulous." Millie admits that she's bad with money, too often speaks before she thinks, and that they're both afraid to commit.

Chuck, 28, a self-employed Tennessean, has most recently worked as a valet, hauler, construction worker and personal trainer. A physically active guy, Chuck holds a BS in Exercise Science from the University of Tennessee, Chattanooga, and enjoys playing tennis and skiing. Chuck likes traveling, but has only been to Mexico and Canada. He speaks no foreign languages. Self-described as being "random, deliberate and kind." His only fears while traveling are "criminals if I had to sleep outside." Considers himself slower than his teammate, Millie, whom he says is "more fearless" and "less thoughtful" than himself. Chuck tries to remain calm under pressure or if upset, but admits to having a "unique pouting manner."
