Actress Mary Willa “Mamie” Gummer and her actor boyfriend Ben Walker are officially engaged to be married. Mamie and Ben, who met while working on a short movie, have been dating for about a year and a half.

“He proposed two days ago,” the actress announced Monday in New York at the Whitney Museum of American Arts Gala, noting that he “surprised” her with a custom-made ring. “He did it on one knee!” she said.

Mamie, the 26 year-old daughter of actress Meryl Streep and sculptor husband Don Gummer, revealed her mom approves of her relationship and loves Ben. A wedding date has not been set yet.
