Sydney Sweeney is ending her 2024 with some fun in the sun … donning a little brown bikini for a jet-skiing adventure.

Check it out … the “Euphoria” star hit the water wearing a cheeky 2-piece swimsuit in order to zip around on a jet ski while out boating in Florida with friends. The actress, who recently wrapped a biopic about female boxer Christy Martin, was unafraid to show off her ripped body … taking a power stance while straddling the watercraft.

She gave fans a glimpse at her toned abs while ditching her waterside coverup at one point during the day out.

Sydney is down in the Sunshine State enjoying some quality time with her fiancé, Jonathan Davino, and other loved ones … entertaining many at her new house in the Florida Keys ahead of the new year.

Sydney is clearly enjoying the benefits of her skyrocketing fame … despite facing harsh criticism about her acting ability earlier in the year.

Remember, Hollywood producer Carol Baum caught quite a bit of flak in April after she suggested Sydney was “not pretty” and couldn’t act … though, she later walked back the comments.
