Happy Birthday, Kristen Stewart! The two-time face of Balenciaga's Florabotanica fragrance, who turns 24 today, is a true style chameleon. The Twilight star can pull off ultra glam as well as she can wear a pair of skinny jeans and plaid shirt—and the same can be said for her beauty choices. Case in point: her deep oxblood lip hue and pompadour ponytail in 2012 versus this year's laidback braided look. "She'd be the perfect face for a campaign for second-day makeup," says the star's makeup artist, Jillian Dempsey. "When hers wears off, she still looks insanely gorgeous."
