Gummer first revealed the couple's exciting baby news in October when she showed off her baby bump at W Magazine's 50th-anniversary party in NYC.

Gummer, the daughter of Meryl Streep, put her bump on display at the event in a form-fitting red sweater dress which she paired with a matching red overcoat and strappy heels.

The couple, who tied the knot in August 2021, stepped out for the special 1972-themed party, where they were photographed together.

The wedded couple celebrated their one-year anniversary in August, with Ronson sharing photos from a gorgeous romantic getaway and a throwback of the happy couple in formal wear.

"When people used to tell me their spouse was their best friend, I thought they were spouting Hallmark nonsense or that they were some freak anomaly of love," he wrote in the caption. "So now I guess I'm either someone who spouts Hallmark nonsense or I'm a freak anomaly of love."

"Or maybe I just married the most incredible human being around. Happy anniversary to my darlingest, you've made me happy beyond my wildest," Ronson added.
