Naomi Watts shows off her stunning diamond wedding band after officially tying the knot with Billy Crudup in Mexico City

Naomi Watts and Billy Crudup walked down the aisle for the second time on Saturday, almost a year after the date of their first courthouse wedding.

And just days after the ceremony, the actress, 55, showed off her stunning diamond wedding ring as she celebrated her one-year wedding anniversary in Mexico.

The Watcher star posted an image to Instagram on Tuesday of her hand resting on her designer bag as she relaxed on a beach to mark the occasion.

Naomi wore her diamond wedding ring with large round stones, and several bracelets on her hand.

“One year and one day,” she simply captioned the image, adding a love heart emoji.

Naomi first sparked rumors that she and Billy were engaged earlier that year, when she debuted a huge diamond with a tasteful marquise cut, along with a diamond-encrusted band.

However, the star declined to confirm the engagement talk, even after American Today host Hoda Kotb directly referenced it during a late April appearance on the morning talk show.

The King Kong star appeared to have worn the ring back in March and she was spotted wearing the sparkler on the red carpet at the 2023 Vanity Fair Oscar Party in Beverly Hills.

Naomi and Billy met on the set of her 2017 Netflix series Gypsy, in which she starred as a therapist who uses an alias to develop close (and unethical) relationships with people closely associated with her patients, while Crudup her husband played.

The costars started dating later in 2017, a year after Naomi split from her partner of 11 years, actor Liev Schreiber.
