Alexandra Daddario dropped jaws in her plunging bikini in 2022, when photos of her enjoying a lake day with sister, Catherine Daddario, went viral. Three years ago, the Baywatch star stripped down to a green-and-white swimsuit while promoting clothing brand Aerie, although fans seemed more interested in her curves than her swimwear label. Displaying her signature assets while looking toned and fit, Alexandra padded around a lake deck before enjoying a paddleboard session, and the snaps earned her quite the compliment. When a user on X reposted a photo from Alexandra’s shoot, they deemed the 39-year-old the “hottest girl on the planet.”

Scroll for all the photos. Earning over 2 million likes for the above Instagram photo, Alexandra twinned with sister Catherine as the two soaked up rays by the water.

Making eyes pop with her ample cleavage, The White Lotus actress went plunging in a teeny bikini, showing off her abs and killer hips while wearing her dark locks down. Meanwhile, Catherine opted for the same fabrics, but in a one-piece swimsuit. “Things we learned today: paddleboarding is harder than it looks. At least we got to be twins for a day in matching @aerie suits,” a caption read.

The fan repost, meanwhile, caught Alexandra in a solo moment. Shot closer up, the mom of one dazzled with her bombshell body, showcasing her killer waistline in her summery, cute bathing suit. “Hottest girl on the planet,” one fan wrote. “Stunning,” another said.

Alexandra became a swimsuit icon in 2017 via her Baywatchmovie role. She’s also known for a racy nude scene in TV series, True Detective. The actress has since toned down her vibe, particularly since her 2024 pregnancy and the October 2024 arrival of her first child. Last fall, she and husband Andrew Form welcomed a son, whose name has not been revealed.

The above Instagram photo was just as popular as Alexandra Daddario caught a cheeky view of her cleavage while lounging around in a flesh-colored bikini.

Displaying her sensational silhouette in tan swimwear, the actress flaunted her toned legs from a towel-topped lounger, enjoying time with pal Kate Eason.

Fast-forward to the end of last year, and Alexandra was making baby headlines. In the above selfie, she held her newborn while writing:

“THIS is what it looks like for me 6 days after giving birth to my magical little baby. Women’s bodies are amazing and I’ve never felt more proud of mine. So much love to all the new moms out there leaning into their new powers (and new @fridamom undies)!” The post netted over 1.3 million fan likes.
