Julianne Hough, 19, is a familiar face on season five of ABC's "Dancing with the Stars." Last year she and her dancing partner, Apolo Ohno, won the competition. Now, alongside Indy 500 Champion Helio Castroneves (seen here), she's determined to win again -- but this time she has to beat her brother Derek, 22, who joined the show this year. (ABC)
