Naomi Watts Is A Vision In Feathered Grey And Silver Dress

Just wait until you see the back.

The Cannes Film Festival needed to roll up the red carpet after Naomi Watts walked it opening night.

The British star looked breathtaking in a grey and silver Elie Saab gown with a feathered skirt and sequined top.

The "Insurgent" actress accentuated the dress' plunging neckline with an intricate silver necklace and her hair was pulled back into a loose bun.

But the frock looked even better when she turned around.

If we couldn't love her enough, Watts' stylist, Jeanann Williams, posted an adorable Instagram shot of her relaxing with little ones Sasha and Kai.

Looks like she needed a quiet moment after all the attention her dress probably garnered!
