Screen star Jennifer Aniston and Nicole Kidman just went for it, flaunting their 40-something selves in chic looks and age-defying grooming at the Feb. 8 New York City premiere of their aptly named new movie "Just Go With It."

Aniston wore a sheer, corset-style Dolce & Gabbana dress with strappy Gucci sandals and a slim clutch. Her platinum hair was down and tousled, for a slightly beachy California-girl look. Another I'm-so-over-the-Rachel-from-"Friends"-hair message, perhaps?

The look was another red-carpet success for 41-year-old Aniston, who's just launched an eponymous perfume line and has been on the talk-show circuit plugging the film, which co-stars Brooklyn Decker and Adam Sandler.

Kidman, meanwhile, stepped out in a leather skirt and blazer by a favorite, L'Wren Scott. She softened its potentially tough edges with a color-of-the-moment blush blouse and towering strappy black sandals. Soft, subtle makeup gave the 43-year-old actress, who's been professing she's so over Botox, a youthful glow.

We can't help wondering if the new BFF's plotted their red-carpet looks when Aniston sat down to chat with Kidman for Harper's Bazaar.
