In the photo, Ratajkowski stands beside a swimming pool, rows of lounge chairs behind her, with a sun-hat in her hand and her hair messily blowing around her face.
You'll notice the photo is captioned "CA," which is clearly referring to Ratajkowski being in California at the time.
The black-and-white photo filter certainly gives the look a vintage vibe.
Ratajkowski has spent her career splitting time between modeling and acting, having been featured on over two dozen magazine covers, and starring in a handful of films and TV shows. She even currently has four films in production.
Her next film scheduled to be released is In Darkness, which is a thriller about a blind musician who "hears a murder committed in the apartment upstairs from hers that sends her down a dark path into London's gritty criminal underworld."
Natalie Dormer and Ed Skrein, both Game of Thrones alumni, will co-star with her in that film.
Just a few months ago Ratajkowski's iCloud was hacked and personal nude photos of her were leaked to the internet.
The hacker had reached out to a reporter in order to try and exclusively sell the images to which the reporter refused and stated to the public, "To be clear, this wasn't footage of a randy star salivating at the mouth wanging their bits about while fishing for a random on Skype for a sex sesh. This was private stuff, sent between two people."
With so much going on in her life, Ratajkowski has clearly earned a poolside getaway.
