Sydney Sweeney shows off incredible bikini body while soaking up the sun at $13 million Florida Keys mansion

Sydney Sweeney showcased her incredible figure as she enjoyed a day under the sun at her $13 million waterfront mansion in the Florida Keys on Wednesday. 

The Euphoria actress, 27 - who was recently seen cozying up to her fiancé Jonathan Davino at the lavish abode - sported a stylish swimsuit while lounging underneath the warm sunshine ahead of the Christmas holiday. 

The star donned a purple-patterned bikini top as well as skimpy, matching bottoms during the relaxing day. 

Sweeney's blonde locks were parted in the middle and swept up into a messy up do to prevent any loose strands from falling onto her face. 

She opted for minimal accessories, and added a pair of mini earrings as well as fashionable, black shades. 

The beauty was spotted staying warm while resting on a lounge chair, and at one point, also took a quick dip in a nearby swimming pool. 

A few days earlier on Monday, Sydney also enjoyed downtime at the home - and was joined by her fiancé Jonathan Davino. 

While looking out at the scenic views, she sat on Davino's lap while also chatting with a female companion who had joined in on the getaway. 

The Anyone But You actress - who has concluded filming a biopic about female boxer Christy Martin - donned a pair of fitted, light blue shorts as well as a long-sleeved, striped short on top. 

Her long hair was parted in the middle, and effortlessly flowed down past her shoulders in natural waves. 

Later in the day, the star was spotted having a blast on the water as she showed off her skills on a jet ski. 

Sydney and Jonathan were first romantically linked in 2018. Four years later, the lovebirds became engaged. 

In regards to weddings plans, Sydney explained late last year in December that she hasn't had much time to begin sorting details for the nuptials.

'I am so busy working! I'm a workaholic and I love it, I love it,' Sweeney expressed to Entertainment Tonight.

Earlier this year in April, Sweeney was spotted leaving a bridal shop in Los Angeles while carrying a large garment bag. 

The pair have also worked together in the entertainment industry. While Sydney starred in the romantic comedy, Anyone But You (2023), she also co-produced the film with Davino through her production company Fifty-Fifty Films.

On having the chance to work closely with Jonathan, the Immaculate actress told the outlet, 'I think it's incredible being able to work with people who you wanna be in business with.'

'It's amazing having someone who cheers you on and someone who fully just supports what you do.'

And a few months earlier in October, the star broke her silence on claims that the businessman from Chicago pays for everything or financially backs her projects. 

'I'm a very successful, independent woman who's worked really hard,' Sweeney told Glamour. 'I've accomplished and bought everything myself, and I provide for myself and my family.' 

'I would love to set the record straight. You can be in a healthy relationship with someone and also be very successful without needing the man.' 

She continued to the outlet, We're teammates. We're in it together. And we want to see each other succeed.' 

The actress has also been focusing on her latest project - a biopic where she portrays female boxer Christy Martin who rose to fame in the 90s. 

Last month in November, Sydney jumped to her main Instagram page to announce that filming had officially wrapped on the movie, and also uploaded a snap as she posed with Christy herself. 

In the caption of the post, the star penned that filming the project 'has been one of the most emotional, transformative experiences of my life.' 

'Christy's journey is so deeply inspiring, and having her by my side during this process was nothing short of surreal.'

'There were moments on set where I'd glance over at her standing by the monitors, cheering us on, and I'd just become so emotional,' Sydney recalled.

'Knowing what she's endured, what she's pushed through to be there in that moment - it made me want to cry.' 

After giving a special shout out to the cast and crew involved in the film, the actress also added, 'This story is so much bigger than just a film.'

'It's a testament to resilience, survival, and finding the strength to keep fighting. I can't wait for you all to see it - not only because I'm proud of the transformation and the work I've poured into it, but because Christy's story deserves to be told...' 

In conclusion, the star wrote that fans will 'witness a story that's as powerful as the woman who lived it. I'll carry this experience with me forever. Can't wait to share more :).' 

Back in October, she shared behind-the-scenes photos to Instagram while sporting brown hair, as well as a sleeveless red shirt and gray sweatpants.

Sydney showed off her muscular arms and wrote in the caption that she has 'been immersed in training to bring to life the story of an incredible woman - a true champion who fought battles both inside and outside the ring.'

'Her journey is a testament to resilience, strength, and hope, and I'm honored to step into her shoes to share her powerful story with you all. more to come soon :).'

David Michôd is directing the film, and told Deadline in May, 'I have a history of making movies about damaged men and I'd been wanting to make a film about a woman with a ferocious energy inside her.'

'When I came across the Christy Martin story two years ago I knew I'd found it,' he added to the publication.

'Her ferocity is intelligible and justifiable and audiences will crave it because of the circumstances she was forced to endure.'

Other stars that have been cast in the project include Ben Foster, Merritt Weaver, Ethan Embry, Jess Gabor, Chad L. Coleman, Tony Cavalero and Katy O'Brien.

Last month, it was also confirmed that the third season of Euphoria will begin production next year in 2025, where Sweeney will reprise her role of Cassie Howard.
