I've been obsessed with Marion's edgy, metallic green nails since their debut at last week's Golden Globe Awards, so I put in a call to her manicurist, Deborah Lippman, for The Scoop:

To compliment Marion's striking Dior dress, Deborah chose a new shade from her signature collection— Don't Tell Mama ($18)— and kept the nails short for a modern finish.

And for red carpet-worthy results at home, Deborah— who also painted the nails of Penelope Cruz (in Night and Day) and Kate Hudson (in Lady Is a Tramp) for the fête— suggests:

— When moisturizing or exfoliating your face, don’t wash the extra product off your hands. Instead, use extra face moisturizer or exfoliator and rub directly into your cuticles. This will keep your hands looking great all year long.
— To get the most out of your manicure, use a regular top coat instead of a quick dry top coat. The regular top coat may take a little longer to dry, but bonds better with the nail polish.
