How radiant is Rachel Weisz at Monday's premiere of "The Lovely Bones"? Those eyes, that lip—
she looks absolutely flawless.

Below, CHANEL Celebrity Makeup Artist Kara Yoshimoto Bua shares how to recreate the actress's latest look:

On the Lips
I was inspired by the color of Rachel's dress, which was calling out for a perfectly red lip! I chose the semi-matte CHANEL Rouge Allure Laque in Dragon. I love this shade because it is a very pigmented blue true red, perfect with Rachel's fair skin, and can be worn very sheer yet give vivid color.

For the Eyes
I wanted shimmery soft eyes to be tonal with the color of the dress so as not to compete with the lips. CHANEL Quadra Eye Shadow in Murano has the most beautiful greenish-gray shimmers that accent Rachel's dark hair and brown eyes. CHANEL Inimitable Mascara in Noir-Black opens up her eyes by lengthening and separating her already thick lashes without any clumps!

On the Face
CHANEL Blush Duo Tweed Effect in Tweed Rose gives her a soft tint of color in the apples of her cheeks.

The Olsen twins made quite the statement at Tuesday's MoMA Film Benefit honoring Tim Burton, with each pint-sized mogul modeling a variety of spring '10 inspired beauty looks.

Now we've come to expect the unexpected from Mary-Kate, who walked the red carpet in a bold, two-toned lip— à la Rodarte— but Ashley's candy-colored highlights? A departure, to say the least.

What do you think of the Olsens' runway-inspired hair and makeup? Brilliant or bust?
