Gaten and Lizzy’s love story is a rare example of a long-term, low-drama relationship that began before both of their careers skyrocketed. Their commitment to keeping their private life relatively sheltered has been a key to their success.

The couple officially started dating in March 2018. At the time, Gaten was already a major star due to the success of Stranger Things, but Lizzy was not yet in the spotlight. They were both just teenagers when they began their romance, laying a foundation of mutual support before the intense scrutiny of Hollywood began.
Major Milestones and Public Appearances
Despite their desire for privacy, they have shared glimpses of their relationship, particularly during significant career moments. They often attend events together, including the prestigious Tony Awards. Their appearances, which are always met with fan adoration, showcase a genuine and comfortable connection.
The Move and Mutual Support (2025)
One of the most recent and significant milestones in their relationship was moving into a new apartment together. This step, which occurred as Gaten was preparing for the highly anticipated final season of Stranger Things and Lizzy was promoting her new projects, signaled a deeper commitment. Gaten has often spoken warmly in interviews about how Lizzy provides a sense of normalcy and stability amidst his chaotic filming schedule.

Gaten has been a vocal supporter of her work, often celebrating her successes on social media, demonstrating a relationship where both partners prioritize and celebrate individual achievement.
