Sadie Sink appears to be single, at least publicly, and that qualifier matters more with her than it does with most young stars. The actress, who officially entered the MCU as Jean Grey in Spider-Man: Brand New Day, has never announced a current partner, and recent celebrity coverage has found no confirmed relationship. Sink has spent years keeping romance, friendships, and most of her off-camera life away from the public gaze, so the absence of a partner announcement does not prove she is privately unattached. It tells us only what she has chosen to make public.
With Stranger Things behind her and Marvel positioning Jean Grey as an important part of its next X-Men chapter, interest in Sink’s personal life was bound to increase. The funny part is that she has spent her career making sure fame gets very little access to it.
Sadie Sink Learned Early to Guard Her Private Life

Sadie Sink’s sparse dating history makes more sense once you hear her talk about growing up famous. She joined Stranger Things at 14, and by her own account, protecting herself became almost instinctive. Speaking with Glamour in 2025, Sink said the demands of modern celebrity increasingly include access to an actor’s personal life:
It’s so hard nowadays with social media.
Sink admitted that she once worried being reserved could hurt her career because young stars were expected to be charismatic, highly visible, and good at feeding the social-media machine. Instead, she went the other way. As she put it, “I didn’t want to talk about my personal life.” That boundary still exists. At Teen Vogue Fest in 2026, Sink acknowledged that losing privacy is one of the sacrifices attached to fame, but said maintaining independence and learning to “live your own life” helped keep her grounded.
Patrick Alwyn Sparked Her Biggest Dating Rumor

The most persistent dating rumor attached to Sink involves Patrick Alwyn, the younger brother of actor Joe Alwyn. Sink and Patrick were photographed spending time together in New York in September 2021, and the sighting quickly generated dating speculation (per Elle). Because Sink had recently worked with Taylor Swift on All Too Well: The Short Film and Swift was then dating Joe Alwyn, fans even floated the idea that Swift had introduced them. No evidence ever established that matchmaking theory.
More importantly, neither Sink nor Patrick confirmed a relationship. ELLE notes that they may just as easily have been friends, and there was no subsequent public romance timeline. That makes Patrick the closest thing Sink has had to a widely reported dating rumor, rather than a confirmed ex-boyfriend.
Caleb McLaughlin Was Never Confirmed as Sadie Sink‘s Boyfriend

Fans have also tried to connect Sink with Caleb McLaughlin, largely because Max Mayfield and Lucas Sinclair became one of Stranger Things’ central young couples. Off-screen, there is no reliable evidence they dated. Sink has spoken warmly about the Stranger Things cast as a support system after growing up together on the series, which is a much firmer description of their bond than the romance theories circulating online.
Their on-screen kiss also fueled some of the curiosity because it was Sink’s first kiss in real life. She later recalled that both actors were awkward and nervous while filming it, but nothing she has said suggests that the fictional Max-Lucas romance continued away from Hawkins (per The Wrap).
Finn Wolfhard and Dylan O’Brien Links Were Never Confirmed

Sink has also been linked online to Finn Wolfhard, but that rumor appears to have originated largely from TikTok speculation. We found no evidence supporting it, and Wolfhard was reportedly involved with someone else when those claims circulated. Then there is Dylan O’Brien, Sink’s co-star in Taylor Swift’s All Too Well: The Short Film. Their performances were deliberately intimate and emotionally bruising, so the internet did what the internet does and tried to turn chemistry into biography.
Neither actor confirmed a romance. Sink later told Variety that when she filmed the project, “I had never been in love,” adding that the kind of breakup depicted in the film was foreign territory to her at that point.
Sadie Sink Has Deliberately Kept Romance Private

The best explanation for why Sink’s dating history is so sparse comes from Sink herself. In a 2025 Teen Vogue profile, she explained that privacy helps her separate herself from the characters audiences watch. Her wording was unusually direct:
I don’t want anyone to know anything about me in my personal life.
She said keeping the public version of “Sadie” smaller allows the characters to come through more strongly. That attitude did not disappear as her fame grew. At Teen Vogue Fest in 2026, Sink spoke about dealing with the loss of privacy that comes with celebrity and said maintaining independence and “live your own life” had helped keep her grounded.
Would Sink ever go public with a relationship, or has she already found the right formula by keeping romance entirely off the celebrity conveyor belt? Let us know what you think below, and follow FandomWire for more on Sink’s next chapter as Jean Grey.
