Stranger Things turned Dustin into the patron saint of heartbreak. Max chose Lucas. Nancy rejected a pizza truce. The Snow Ball handed him pain like it was party decor. Yet destiny enjoys plot twists, because Gaten Matarazzo now stands beside a certified baddie named Lizzy Yu, an actress who has built a stranger world of her own, glowing with Avatar fire and cinematic authority.

While Dustin’s fictional tears filled Hawkins hallways, Gaten Matarazzo’s reality carved a universe where confidence walked beside him, and the heartbreak storyline packed its bags.

Gaten Matarazzo’s girlfriend is Elizabeth 'Lizzy' Yu. She is the same scene-shifter who brought Princess Azula to life in Netflix’s live-action Avatar: The Last Airbender. Their journey began in 2018. They appeared at red carpets, Instagram dumps, and her senior prom with an ease that felt cinematic. They now live in New Jersey with three cats who monitor their schedules with judgment that rivals any royal firebender.

Lizzy Yu is far more than Matarazzo’s girlfriend. She is a rising force with roots in Korean, German, Irish, and Polish heritage that add texture to every character she plays. Her work includes Avatar, May December (2023), and Somewhere in Queens (2022). Her energy moves between indie quiet and blockbuster confidence. She feels like the kind of actor who turns every room into a launchpad.

As Lizzy Yu’s ascent accelerates, the Stranger Things cast continues its cosmic love lore, where each pairing sparks theories that glow brighter than Hawkins streetlights.

The Stranger Things constellation of real-life romances keeps expanding like it is auditioning for its own spin-off. Fans follow each love story with the kind of fascination usually reserved for Demogorgon encounters. Millie Bobby Brown and Jake Bongiovi lifted the fairytale standard higher than Hawkins' power lines. Natalia Dyer and Charlie Heaton built a steady rhythm that feels like a soft indie track. Every couple becomes instant lore before the fandom even settles.

Winona Ryder, the forever-ethereal Joyce Byers, continues a long-term chapter with fashion designer Scott Mackinlay Hahn, a pair that radiates calm in a universe that thrives on chaos. Joe Keery, meanwhile, shook the internet after being handcuffed during Sabrina Carpenter’s show, a moment that launched a thousand theories. Nothing stands confirmed, yet the rumour mill runs with a confidence that rivals any Hawkins plotline.
