Brooklyn Decker may be an all-American beauty, but she can easily transform into a blonde bombshell (exhibit A: her steamy Sports Illustrated cover). Decker has tapped into both personas since she's taken on acting roles on TV shows like Chuck, Ugly Betty, and Royal Pains.

When she's not working, Decker, who's married to tennis pro Andy Roddick, likes to keep her makeup low-key. "Sometimes I'll add mascara and some lip balm, but other than that I like to let my skin breathe between photo shoots and filming," she says. "Once in a while, I'll put on a funky, colorful lipstick." Here's what this no-frills starlet considers her beauty essentials.
