Julianne Hough posed to show off her exposed back on the red carpet of the People's Choice Awards in LA this evening. Julianne is coming off a bikini-filled vacation in St. Barts with boyfriend Ryan Seacrest, though he wasn't by her side for this evening's arrival. While on the tropical getaway, Julianne actually made sure to stay fit by hitting the stationary bike in her tiny two-piece suit. What do you think about her daring number?
