Naomi Watts and Billy Crudup tie the knot in New York City

British-born Australian actress Naomi Watts and US star Billy Crudup have stunned famous friends with news of a surprise wedding this weekend.

Naomi Watts confirmed she tied the knot with Billy Crudup after Page Six exclusively reported that the pair was seen with matching wedding rings.

“Hitched!” the British-born Australian actress, 54, captioned on Instagram a photo of herself and her new husband, also 54, on the steps of a courthouse Saturday.

Several stars congratulated the happy couple on their nuptials.

“YESSSSS,” wrote Olivia Wilde, with a string of heart emojis.

“Congratulations,” wrote Miranda Kerr, while Lisa Rinna added, “Yay!!!!”

Watts and Crudup were spotted a day earlier returning to their New York City apartment in wedding attire.

The King Kong star was photographed Friday wearing a white Oscar de la Renta Sweetheart Water Lilly Guipure dress while holding a bouquet of white flowers in hand.

Meanwhile, the Almost Famous star wore a navy blue suit and a white button-up shirt.

Both noticeably had wedding bands on their left hands, sparking speculation that they had just gotten married.

The couple has kept most of their relationship private throughout the years.

In April, the King Kong actress dodged questions about the huge rock she was wearing on her left ring finger.

When Today host Hoda Kotb pointed out the “beautiful” jewellery, Watts simply laughed before co-host Savannah Guthrie tried to get more details.

“Hoda is asking if you’re engaged,” Guthrie bluntly asked, to which the actress avoided answering by blaming her “brain fog.”

Crudup and Watts confirmed that they were dating in 2017 while filming the Netflix drama Gypsy.

Page Six exclusively reported at the time that they were spotted holding hands in Tribeca.

However, the pair did not make their red carpet-debut until the 2022 SAG Awards.

Before dating Crudup, Watts dated Liev Schrieber for 11 years. The pair split in 2016 and share two children — Sasha, 15, and Kai, 14.

The Big Fish actor, on the other hand, shares 19-year-old son William with ex Mary-Louise Parker, whom he left at seven months pregnant for Claire Danes.
