Sydney Sweeney and Glen Powell have reignited romance rumors as she posed without her diamond engagement ring from fiancé Jonathan Davino.

The 27-year-old actress steamed up the Instagram feeds of millions as she posted a gallery of sultry beach snaps taken by photographer Amber Asaly on Friday.

And one person the images caught the eye of was her Anyone But You co-star Powell, 36, who liked the post leading to many fans to remember their red hot romance rumors as they filmed and promoted the 2023 romantic comedy.

Other celebrities who liked the image included Kylie Jenner, Jessica Alba, Emily Ratajkowski, and Jax Taylor.

However,  it was certainly Glen's like which was the most eyebrow-raising of all as rumors surrounding his supposed romance with Sydney spiraled out of control as the pair filmed Anyone But You together in Australia - with fans saying their chemistry off-screen was undeniable.

The gossip flurried even more after the news hit that Powell had broken up with his girlfriend of over three years, model Gigi Paris, in April 2023 - just months after his onscreen romance with Sweeney was filmed.

Powell has previously admitted that he and Sweeney agreed to 'play up' the dating rumors as publicity for the rom-com as she was in a committed relationship with fiance Davino at the time. 

When asked about their decision to lean into their characters, Ben and Bea, Powell opened up about utilizing their 'authentic chemistry' to entice viewers to watch their rom-com.

'I  don't have the mental capacity to pull anything like this off, but she's very smart. She's very smart,' the Top Gun: Maverick actor told Business Insider. 'I had such a wonderful journey with her on this thing. But in terms of actual dating and actually being together? [Laughs.]' 

As for how their chemistry on-screen and natural rapport at press events may have created a 'lot of headaches for' him, the performer acknowledged his split from Gigi Paris. 

'Well, look, the only reason it made things harder for me to lean into that stuff was that I was going through a very real breakup amidst a promotional tour,' he explained.

Powell continued: 'I was with someone that I really loved and cared about and was trying to kind of make sense of a lot of stuff.'

He has also admitted that he and Sweeney 'love each other,' but are not romantically involved.

Meanwhile, in the new social media photos Sydney was on a beach as she showed off her stunning figure in a pink-and-white Dior minidress in the images.

She was made up for the camera as she moved about a sandy beach before sunset.

This comes after the siren 'called off their wedding' as she shared a video of herself underwater on Thursday.

Amid reports that she and Davino, 41, are figuring out whether or not their relationship can be saved, the actress appeared to be seeking solace by going for a swim. 

The Anyone But You star could be seen striking various poses as she floated in a large pool, blew bubbles and reached up toward the surface while rocking a white string bikini in footage captured by celebrity photographer Amber Asaly. 

The Euphoria actress showed off her toned frame in the tiny two piece as she leaned back and looked toward the sky. 

The sultry clip was tellingly soundtracked to heartbreak anthem, Wicked Game by Chris Isaak.

Within an hour, she received more than 1.6 million likes from her Instagram followers as well as thousands of comments from fans describing her as a 'real life mermaid.'

The Emmy nominee and her longtime partner started dating in 2018 and got engaged in 2022, but for the most part kept their relationship assiduously private.

However a source recently revealed to DailyMail.com that the pair have postponed their wedding, which was planned to take place this May.

The insider explained that the couple were undergoing a 'rough patch' and trying to 'reassess' whether they ought to remain together at all.

Sydney further fueled speculation this week when she deleted a picture of her and Jonathan kissing from an Instagram album she had posted to celebrate the new year.

Earlier this week, another source claimed the pair 'called off the wedding' altogether but have yet to break up, via Us Weekly.

Jonathan and Sydney have not been seen together since January, and she has purportedly been staying at the Beverly Hills Hotel since mid-February.

'Sydney and Jonathan have been having major issues but are not fully split. Things are not great right now, but they aren’t throwing in the towel yet. They are working on their relationship but have called off the wedding for now,' the insider said.

'They were supposed to get married this spring. The wedding is not happening, and they aren’t having further discussions about it. Sydney wanted to cancel everything and couldn’t handle the stress,' the source alleged.

'A lot of their issues stem from Sydney being extremely busy with work commitments,' the insider claimed further.

Sydney has a cavalcade of projects in the pipeline, including a return to her star-making show Euphoria, on which she plays Cassie Howard.

She is slated to star in remake of the 1960s Jane Fonda classic Barbarella, and has already filmed a biopic of pioneering 1980s boxer Christy Martin.

The actress also recently wrapped a movie called The Housemaid alongside It Ends With Us actor Brandon Sklenar, and she is signed to the role of Kim Novak in the film Scandalous! about the Old Hollywood icon's romance with Sammy Davis Jr.

Sydney, according the insider, 'doesn’t have a lot of downtime, and it causes tension in their relationship. Sydney is really focused on her career. Jonathan wishes they were able to spend more quality time together.'

The source added: 'Things are also always tense between them when she is promoting a movie because she has to give her full attention to the project, and people always speculate about their relationship and Sydney being close to her costars. It’s a tough dynamic for Jonathan.'

In 2023, when Sydney and Glen Powell were promoting their romantic comedy Anyone But You, they were hit with rumors they had an on-set affair - and deliberately played into the conjecture in order to drum up publicity for the movie.

Glen freely admitted that the gambit 'worked wonderfully,' as the picture was a smash hit, and he added to the New York Times: 'Sydney is very smart.'

The fresh claims come after a source informed DailyMail.com: 'Sydney and Jonathan are in a rough patch with their relationship, and they have decided to stay away from each other to reassess if it is more important to save their relationship or move on.'

Sydney's 'career is booming, and she is nurturing that,’ the insider observed. ‘To settle down now might be the wrong thing to do. Sydney wants a family, wants to be married, but not as soon as she originally anticipated and not as soon as Jonathan wants. So, there is a disconnect between them both.'

The source added that they 'don't want to break up officially, but friends fear that is where they are heading,' noting: 'He's older than her and she is just getting into a big part of her life professionally. She has to figure out what is most important to her.’

As long ago as 2023, Sydney confessed that she was not able to focus on her wedding plans because 'I am so busy working! I'm a workaholic and I love it, I love it,' in an interview with Entertainment Tonight.

Last year, Sydney candidly shared that her drive to earn money was rooted in the financial difficulties she saw her family suffer during her upbringing.

'I come from a family where I saw my parents lose everything, and I am terrified of that. That fear will always be instilled in me,' she told Glamour.

'I’m a huge saver. I don’t just go and spend money. I like to invest. I like real estate. I like making, hopefully, smart choices with the money I’m making. But I don’t think I’ll ever actually feel comfortable.'

In addition to being romantically involved, Sydney and Jonathan are business partners, running the production company Fifty-Fifty Films.

She recently repudiated rumors that Jonathan provides the monetary backing for the whole enterprise, insisting: 'You can be in a healthy relationship with someone and also be very successful without needing the man. We’re teammates. We’re in it together. And we want to see each other succeed.'
