Alexandra Daddario is engaged to 52-year-old producer Andrew Form, her rep confirms. Daddario was spotted with a diamond ring on that finger while running errands in Los Angeles. The two appeared to make their relationship Instagram official this past spring. In one PDA-packed post from May, Daddario captioned their picture, "I love you… and even that is an understatement." They then made their red carpet debut as a couple in July when they attended The White Lotus premiere in Pacific Palisades, Calif. In the HBO Max hit, Daddario played Rachel, a journalist who recently wed Jake Lacy's character Shane and began to reevaluate her life during their honeymoon at a Hawaiian resort. While they tend to keep their personal lives out of the public eye, Daddario and Form have given fans a few glimpses into their romance by sharing snapshots on social media, capturing everything from their travels to their everyday life at home.
