Naomi Watts showed how to do casual courthouse chic for her wedding to Billy Crudup.

The actors, both 54, got married in New York City on Saturday after six years together.

For the understated ceremony, Watts wore a guipure lace Oscar de la Renta gown with a sweetheart neckline and delicate straps made from water lily motifs.

She paired the almost-floor-length dress, which can be purchased online for $4,990, with gold strappy heels by Gianvito Rossi and a diamond necklace by Anita Ko, Vogue reported.

Watts shared a photo of the look on Instagram on Saturday with the caption, "Hitched!"

She was also spotted outside the courthouse wearing chic cat-eye sunglasses.

She carried a bunch of white flowers tied with a white ribbon. In a photo shared to an Instagram Story, she wrote, "Flowers from the deli!!"

As Vogue reported, it seems that Watts was initially planning to wear something she already owned to the nuptials. She wrote on her stylist Jeanann Williams's Instagram page, "thanks for talking me into going beyond my own closet and sending me the gorgeous dress !!"

Watts and Crudup were friends for years before becoming romantically involved, Insider's Charise Frazier reported. Then, after they played a couple in a 2017 Netflix drama, "Gypsy," reports emerged that they were dating. They made their first red-carpet appearance together five years later, at the 2022 Screen Actors Guild Awards.
