Naomi Watts is officially off the market.
Naomi captioned her June 10 post, "Hitched," alongside a photo of her looking lovingly at Billy as they posed in front of what appeared to be a Manhattan courthouse. In the same snapshot, the Watchmen actor was smiling from ear to ear and wrapped his arms around Naomi.
As for their wedding attire, the newlyweds dressed to impress.
The King Kong actress wore an intricately floral embroidered bridal gown by Oscar de la Renta, which perfectly coordinated with her white bouquet that was plucked straight from "the deli," she revealed in an Instagram Story. For the groom's part, he looked dapper in a navy blue suit with a white button-down.
After Naomi shared the news, she and Billy received an outpouring of love from their famous friends in the comments section.
Naomi's ex, Liev Schreiber, who she shares kids Sasha, 15, and Kai, 14, with, also commented on her marriage news.
"Congratulations!!!" he shared. "Gorgeous!!!"
Billy is also a dad to son William Atticus Parker, 19, whom he shares with ex-Mary Louise Parker.
Back in April, engagement rumors swirled around after the actress was spotted wearing a massive diamond ring on that finger. When asked about her relationship milestone during a Today appearance, she played coy.
"My eye is hurting," Hoda Kotb said. "There's a big glint coming from some ring over here. It just struck me. But it's beautiful."
The actress cheekily responded, "Oh, the brain fog!"
Naomi and Billy's low-key wedding comes as no surprise, as they've been keen on keeping their relationship private. In fact, the two, who played spouses on Netflix's Gypsy, first sparked romance rumors in July 2017 and have since kept their love life under wraps.
But the couple isn't the only newlyweds to have a surprise wedding. Keep reading to see who else got secretly hitched.
