Alexandra Daddario’s Best Bikini Moments Through the Years

Alexandra Daddario may be best known for projects like The White Lotus, Mayfair Witches and Percy Jackson & the Olympians: The Lightning Thief, but the 40-year-old actress also loves to lounge poolside on her days off.
Daddario’s art and preferred leisure sometimes cross over, as well: She was featured in the 2017 film Baywatch, where SI Swimsuit’s very own Kelly Rohrbach portrayed Pamela Anderson’s famed character, C.J. Parker. Daddario, a New York native, is currently working on a number of film projects, including Hershey, in which she stars opposite Finn Wittrock as Kitty and Milton Hershey, respectively. Daddario is also connected to the forthcoming film Happy Life, which she is set to star in alongside The Studio’s Ike Barinholtz and Lost’s Evangeline Lilly.

In addition to her work in front of the lens, Daddario has produced several films, including Can You Keep a Secret? and We Summon the Darkness. She is also a proud mom and brand ambassador for Christian Dior, TAG Heuer and other notable brands.
From the big screen to the beach, Daddario is one to watch. Below, take a look at some of her greatest swimwear moments throughout the years.
