Prepon, the former “That ’70s Show” star who’s currently on “Orange Is The New Black,” announced the news Sunday with a sweet black and white photo of the two presumably on their big day.
“Wishing all of us the good stuff!” she wrote.
They welcomed a baby daughter, Ella, in August.
TMZ reported that Prepon, 38, and Foster, 37, were spotted getting their marriage license last month in New York, so the nuptials didn’t come as too much of a surprise.
Foster, who appeared in “X-Men: The Last Stand” and “Hostiles,” was previously engaged to Robin Wright.
