ROSY LIPS

We're usually too busy gushing over Rosie Huntington-Whiteley's insane body to notice her makeup, but the jolt of bright pink on her lips has officially gotten our attention. To steal her just-bitten look, first exfoliate lips with a scrub, like Fresh Sugar Lip Polish, to get rid of any dry flakes. Then apply a vivid, rosy lipstick, like Dior Addict Lipstick in It Pink. "Make sure you pat and blot with a tissue so the color doesn't look too heavy before topping with a clear balm," Baraf says.

SHADOWY CAT EYES

Mila Kunis's diffused cat eyes somehow look both soft and bold, and just the right amount of slept-in. To get the look, rim the inside of the eyes with a black pencil (try Estée Lauder Artist's Eye Pencil in SoftSmudge Black), smudging along the lower lash line. Then brush a neutral shadow into the crease, says makeup artist Meredith Baraf. Next, dot the outer corners with liner. Using a Q-tip, drag the mark outward half an inch. Lightly dip an angled eye-shadow brush into a soft black shade like M.A.C. Eye Shadow in Print and swipe on top. Blend with a fluffy brush and pile on tons of mascara.

RED LIPS AND PINK CHEEKS

"Red lips are nothing new," Sobol says. "But what makes Emma Watson's look so modern is pairing them with pink cheeks." To get the most natural, just-rolled-around-in-the-hay flush, swirl a pink blush, such as Nars Blush in Gaiety, below the apples, over the center of the cheeks, she says. Paint on a true red lip color with a lip brush—we like Yves Saint Laurent Rouge Pur Couture Pure Colour Satiny Radiance Lipstick SPF 15 in 01. For a long-wearing finish, try Sobol's trick: "Hold a tissue over the lips, tap loose powder over the tissue, and then peel it away. It takes away shine and makes the color last for hours."

NOT-SO-SMOKY EYES

For those intimidated by heavy smoky eyes, Megan Fox's softer version delivers the same sultry effect. Line the inner rims with black or brown liner, then smudge along the top outer corners. Apply a wash of champagne (such as CoverGirl Eye Enhancers in Champagne) across the lids and blend. Using the same shadow, line the lower lashes and place a dot at the inner corners to instantly brighten up eyes. Individual falsies placed at the outer corners finish the look, says makeup artist Susie Sobol.
