The Batman star, 37, and Harry, 32, first sparked dating rumours in August 2025 when they were seen strolling through the streets of Italy.
Since then, they've been pictured several times, enjoying low-key outings in New York, London, and Rome, and now, fans are convinced the couple is engaged.
While neither has commented on their relationship status, Harry wouldn't be Zoë's first fiancé.
The actress has been engaged twice, but only one ended with a wedding (and subsequent divorce), while the other ended around a year after the proposal.

"All my relationships in life – my friendships, my romantic relationships, my family – the journey is learning how to show up honestly," she told Elle in 2022. "Sometimes we can't show up, and that's okay as long as we know how to communicate that we love those people."
The star was in a relationship with fellow actor Ben Foster from 2007 to 2009. The X-Men star was eight years older than Zoë at the time and they made their first public appearance together at a fundraising gala.
Although their romance was never officially confirmed nor denied, Zoë and Ezra were romantically linked from 2010 to 2011. The pair met during the casting for their 2010 film Beware the Gonzo. "Ezra had the part and we met, before I was actually hired, just to get ready for a chemistry read, and there was chemistry. We became best friends immediately, and still are," she told Collider in 2011.
Zoë dated the Gossip Girl alum from 2011 to 2013. Penn revealed that the pair had met in New York while he was filming the hit show and she was living in Brooklyn. He described their romance as "real, true, earth-shattering love" in an interview with Movieline.
The star was spotted with Chris Pine at a Coldplay concert in September 2014 and they later attended a party together at Tao Nightclub during the Sundance Film Festival. The pair remained on amicable terms and Chris even attended Zoë's rehearsal wedding dinner to Karl Glusman in 2019.
Although Zoë dated the Canadian rapper in 2013, their relationship wasn't confirmed until 2017. During an appearance on Watch What Happens Live, a viewer asked the actress if the pair had ever dated. "We hung out for a minute. But we are very good friends. You know….We hung out a little bit. You know, it’s like how I hang out, I don't know how you hang out…" she replied.
The pair met in 2015 when Zoë's band, Lolawolf, opened for Twin Shadow on tour. During a chat with Nylon in 2015, Twin Shadow gushed over the actress and shared that she has a "big heart". "Zoë really is so down-to-earth. She surprises you with how natural she is," he said.
The former couple met through a mutual friend in 2016. "I love that it wasn't on an app and that it wasn't on a movie set. My friend knew that I wanted to meet someone – not even to get serious, I think just to get laid, to be completely honest with you – and he brought Karl. I instantly felt something," she told Vogue in 2019.
Zoë and Karl got engaged in February 2018 and tied the knot in July 2019 at her father's three-story, 18th-century mansion in Paris. However, following 18 months of marriage, Zoë filed for divorce, which was finalized in 2021. The actress told ELLE in 2022 that Karl is an "incredible human being" and their divorce was "less about him and more about me learning how to ask myself questions about who I am and still learning who I am, and that being okay. That’s the journey I’m on right now."
"I just learned to think about who I am and what I want," she told GQ in November 2022. "You meet someone who’s amazing and wants to marry you, and there’s nothing wrong with that. If there’s nothing wrong, then why wouldn’t you do it? You love them and that’s what you do. It’s a hard question to ask yourself: 'Maybe I don’t want the thing that I’m supposed to want, a marriage, children, any of it. I don’t know if I want that at all.' That’s an uncomfortable question, especially for a woman to ask herself."
Zoë and Channing were in a relationship from 2021 to 2024. In a November 2022 interview with GQ, she called Channing "a wonderful human: and that they bonded over their mutual love of art and movies. "He makes me laugh and we both really love art and talking about art and the exploration of why we do what we do. We love to watch a film and break it down and talk about it and challenge each other."
The pair got engaged in October 2023, but the romance was short lived as they parted ways a year later. Two months after their split, Zoë credited Channing's "charisma" in his role in Blink Twice in an interview with Variety.
"I love this thing that we made together, and I care for him very much... I’m so happy that all of it happened. I just feel so grateful that we got to go on that journey together," she told ELLE in March.
She added he "has so much more coming, and I think he’s in a place as an actor where he’s feeling really confident and people are seeing different sides of him. He’s got a lot to offer, so I’m excited for people to keep witnessing that."
