Actress Sydney Sweeney marked her birthday weekend with a lake trip that quickly drew attention online after she shared a series of swimsuit photos that fans dubbed her “trip to Mars.”

As Y Entertainment! reported, the Euphoria star posted the collection of images and clips to Instagram, highlighting moments from the getaway with friends. The set included three different swimsuit looks, along with activities such as wakeboarding and exploring canyons.

The first image showed Sweeney posing on a rock in the middle of a lake while wearing a deep-neck monokini with a front zipper, paired with sunglasses. Another photo captured her on a boat alongside a friend, followed by a short video of her jumping into the water.

Later slides revealed Sweeney in a white, strappy monokini while exploring canyons.

She then changed into a sparkly gold two-piece swimsuit, layered with a sheer blouse and a cowboy hat.

The trip also featured food, parties, and lakeside celebrations, which were included in her post.

The photos quickly circulated online, prompting speculation about the trip’s location, with some commenters suggesting it was Lake Powell.

Fans described the pictures as “out of this world,” with one calling her a “space cadet” and others referring to her as both an “icon” and a “Barbie.”

The images were shared under the caption referencing a “trip to Mars,” which helped fuel the online response. The set has continued to draw reactions as fans discuss the mix of styling, location, and Sweeney’s choice of swimwear.

Sweeney, who has become a rising name in Hollywood through roles in HBO’s Euphoria and other projects, has built a significant following on social media, where posts like this often gain rapid attention.
