Transformation

As Kim Bauer on 24, Elisha Cuthbert spent almost a decade wearing the same hair and makeup look. Perhaps as a result, her off-screen look is full of variety. "It's fun for me when I get to try new things," she told InStyle. The Happy Endings actress set trends when she chopped off her (and Kim's) chin-length bob in favor of a sexy pixie that not only complemented her strong features, but gave her something her most famous character would appreciate—free time. "It takes me two seconds to shampoo and condition," she told People. "Two seconds to blow-dry. It becomes more about you instead of what you have to do to feel good."

The blond Calgary native (and star of My Daughter's Secret Life) subtly enhanced her translucent complexion for the Teen Choice Awards.
