From teen dramas to superhero sets, these co-star romances prove on-screen chemistry doesn’t always stay fictional.

There are very few things that have the internet in a chokehold than a celebrity romance. Give us a blurry fan photo or two co-stars looking a little too comfortable together, and suddenly we're all armchair detectives. 

This probably explains why rumours surrounding Off Campus stars Mika Abdalla and Josh Heuston have spread so quickly. While neither has publicly addressed the social media speculation, fans have been closely watching their interactions, with a recent fan-captured moment in Paris adding even more fuel to the fire.

BuzzFeed has reached out to Mika Abdalla’s and Josh Heuston’s representatives for comment. 

Either way, Mika and Josh are far from the first stars to spark dating rumours after sharing the screen. From superhero sweethearts to teen drama favourites, here are some of the most memorable co-star couples over the years.

From teenage superheroes to one of Hollywood’s most-loved couples, Zendaya and Tom Holland’s romance has been years in the making. 

The pair first crossed paths while filming Spider-Man: Homecoming in 2016, and spent years ignoring dating speculation before fans finally got the photo confirmation they’d been waiting for in 2021 after paparazzi pictures emerged. 

The pair have reportedly since tied the knot, with Holland seemingly confirming the news with a six-word response.

If you were a teenager in the late 2000s, chances are you were fully invested in Zac Efron and Vanessa Hudgens. 

After meeting as Troy and Gabriella in High School Musical, their real-life romance quickly became almost as iconic as the films themselves. They spent more than four years together before calling time on the relationship in 2010, but their shared Disney-era history still has fans reminiscing whenever either of them mentions East High.

Miley Cyrus and Liam Hemsworth’s love story had more twists than most romantic dramas. After meeting while filming The Last Song, the pair spent nearly a decade navigating breakups, reconciliations, engagements and eventually marriage. 

They tied the knot in 2018, but announced their separation less than a year later, finalising their divorce in early 2020.

Turns out Serena van der Woodsen and Dan Humphrey weren’t the only ones falling for each other. Blake Lively and Penn Badgley quietly dated while filming Gossip Girl, managing to keep much of their relationship away from the spotlight despite starring in one of the biggest teen dramas on television. 

They split in 2010, but impressively kept the breakup under wraps for a while, proving they were just as good at keeping secrets as their Upper East Side alter egos.

Few co-star couples had fans rooting harder than The Vampire Diaries stars Nina Dobrev and Ian Somerhalder. Their off-screen romance blossomed while the supernatural drama was at the height of its popularity.

After dating for around three years, the pair went their separate ways in 2013, though they remained professional while continuing to work together on the series.

Long before celebrity couples were hard-launching relationships on Instagram, Kristen Stewart and Robert Pattinson had the world watching their every move. 

After meeting as Bella Swan and Edward Cullen in Twilight, their romance became almost as famous as the vampire franchise itself. Following several years of on-and-off dating, the pair eventually split in 2013, bringing an end to one of the defining celebrity relationships of the late 2000s.

The pair met while filming Gigli in 2002, and quickly became the centre of tabloids, with their relationship dominating headlines throughout the early 2000s. They got engaged, sparked endless public fascination and seemed destined for the long haul before ending their relationship in 2004, cementing their place in celebrity-couple history.

The pair rekindled their romance in 2021 and married in July 2022, but they officially filed for divorced in August 2024.

Emma Stone and Andrew Garfield gave fans yet another reason to become emotionally invested in a Spider-Man love story. After meeting on the set of The Amazing Spider-Man, the pair quickly became one of Hollywood’s most adored couples thanks to their chemistry both on and off screen. 

Their relationship came to an end in 2015, but they’ve remained on good terms ever since, with both speaking fondly about one another in the years that followed.

Jennifer Aniston and Vince Vaughn struck up a romance while working on The Break-Up. Their relationship began shortly after Aniston’s split from Brad Pitt.

 Although they eventually split in 2006, Aniston later spoke warmly about Vaughn and the positive role he played in helping her move forward during that chapter of her life.

“I call Vince my defibrillator,” she told Vogue in 2008. “He literally brought me back to life. My first gasp of air was a big laugh! It was great. I love him. He’s a bull in a china shop. He was lovely and fun and perfect for the time we had together. And I needed that. And it sort of ran its course.”

For a generation of romantics, Rachel McAdams and Ryan Gosling dating in real life felt like The Notebook had somehow escaped the screen. The pair got together after filming the beloved romance and became one of Hollywood’s most talked-about couples. 

Despite spending years making long-distance work, they eventually called it quits in 2007.
