Sebastian Stan and Annabelle Wallis: What Most People Get Wrong

If you’ve spent any time on the corner of the internet where people dissect every grainy paparazzi photo of Marvel stars, you already know the deal. Sebastian Stan has always been the king of the "low-key" relationship. He doesn't do the big Instagram reveals. He doesn't post "happy anniversary" captions with twenty heart emojis.

Honestly, he barely talks about his personal life at all.

But since 2022, things have changed just a little bit. He’s been with British actress Annabelle Wallis, and while they are still famously private, they’ve started showing up in places we actually see them. Last year, at the 2025 Golden Globes, he did the unthinkable. He won Best Actor for A Different Man and, right there on stage, said, “Annabelle, I love you.”

People lost their minds. It was basically the celebrity equivalent of a hard launch after three years of "are they or aren't they?"

The Timeline Nobody Actually Tracks

Most people think this started recently. It didn’t.

They were first spotted back in May 2022 at Robert Pattinson’s 36th birthday party. There was a photo—now deleted, of course—of Wallis basically biting his lip. It was chaotic. It was very New York. But after that? Total radio silence for months. That’s how they operate. They’ll go for a walk in the West Village with her dog, Zeus, get photographed once, and then vanish for an entire season.

Why the 2025 Golden Globes Changed Everything

Before January 2025, you could arguably say they were just "hanging out." But when they walked the red carpet hand-in-hand, the narrative shifted. Wallis was in this shimmering pink Wiederhoeft gown—total Barbiecore vibes—and Stan was in a black suit with white trim.

They looked like a couple. Not just two famous people at the same event.

Then came the shout-out. For a guy who told Vanity Fair in April 2025 that he tries to keep his relationship for himself because privacy is impossible nowadays, that public "I love you" was a massive deal. It confirmed that this wasn't just a fling. They’ve been together through his transformation into Donald Trump for The Apprentice and his intense work on Thunderbolts*.

What You Should Know About Annabelle Wallis

If she looks familiar, it’s because she’s everywhere. She was Jane Seymour in The Tudors. She was Grace Burgess in Peaky Blinders (the one who actually broke Tommy Shelby’s heart). She even fought mummies with Tom Cruise.

But here’s the interesting part: she’s just as private as he is.

She previously dated Chris Pine for about four years. Before that, she was with Chris Martin from Coldplay. She’s used to the spotlight, but she clearly prefers to stay on the edge of it. She doesn't use Stan for "clout." In fact, when he got his first Oscar nomination in early 2025, she just posted a screenshot on her Instagram Stories with "SEBASTIAN!!!!! yeaaaaahhhhh!!!!" written over it. Simple. Real.

The "PR Relationship" Rumors

Look, whenever two attractive actors date, the "it's for PR" comments start flying.

People claimed they were only together to boost his awards season chances for The Apprentice. But if you look at the evidence, that doesn't hold water. They were together long before that movie even had a trailer. They were seen having lunch with his Pam & Tommy co-star Lily James in 2023. They spent his 40th birthday in Greece.

PR stunts don't usually involve walking a dog in the rain or grabbing smoothies at Erewhon when no one is looking.

A Quick Glance at the Past

Sebastian’s dating history is basically a "who's who" of 2010s television.

• Leighton Meester: His first "serious" love. They met on Gossip Girl. He recently admitted that life felt simpler back then.
• Jennifer Morrison: Met on the set of Once Upon a Time.
• Margarita Levieva: They were together for a couple of years and stayed friends.
• Alejandra Onieva: The Spanish actress he dated during the pandemic.

Notice a pattern? He tends to stay in long-term things. He isn't a serial dater. He’s a relationship guy.

Why They Work in 2026

As of January 2026, the two are still going strong. Just a few months ago, they were seen in Rome, looking very much like they were on a permanent vacation. They’ve mastered the art of being "publicly private."

They attend the BAFTAs and the Oscars together, but they don't do joint interviews. They support each other’s work—she was right there for the A Different Man premiere afterparties—but they don't make their love the "brand."

In a world where every celebrity couple has a joint TikTok account, there’s something kind of refreshing about that.

What’s Next for the Couple?

Sebastian is currently circling the role of Harvey Dent in The Batman Part II. He’s busier than ever. Annabelle is filming her own projects. But if the last three years have taught us anything, it’s that they prioritize the "normal" stuff.

Don't expect a wedding announcement on the cover of People. Don't expect a pregnancy reveal via a curated photoshoot.

Expect more blurry photos of them in Los Angeles, more rare red carpet appearances where they actually look happy to be there, and maybe—if we're lucky—another shout-out at an awards show.

Actionable Insights for Fans:

• Ignore the "Breakup" Clickbait: Unless you see it on a reputable trade site or they stop appearing together at major events, they are likely just staying out of the way.
• Check Her Stories: Annabelle rarely posts him, but when she does, it’s usually to celebrate a major career milestone.
• Respect the Boundary: Stan has been vocal about how much he values his "one part of life" that stays his. Supporting his work is the best way to show love for the actor without invading his space.

The reality is that Sebastian Stan and Annabelle Wallis are probably the most stable couple in Hollywood that you aren't talking about enough. And that's exactly how they want it.
