The Famous 'Marriage Pact' and How Jake Bongiovi Changed Everything

The most viral aspect of the Millie-Noah dynamic has always been their now-famous "Marriage Pact." This lighthearted agreement became a symbol of their deep, non-romantic commitment to each other.

1. The "Single at 40" Rule

The pact was simple and hilarious: Millie and Noah agreed that if they were both still single by the time they turned 40, they would marry each other. They were quick to clarify that this would be a purely platonic union, a way to ensure they would always have each other and never be alone.

They jokingly noted that the marriage would have to be child-free, stating, "Because we wouldn't be able to have kids together, 'cause that's, like, my brother."

2. The Anti-Romantic Clause

Crucially, the pact was always framed with a major caveat: it was purely a friendship commitment. Their relationship has consistently been described as brother and sister, a platonic soulmate connection rather than a romantic one. This distinction is vital to understanding their dynamic and the nature of the pact itself. They view each other as family, and their on-screen chemistry as Eleven and Will Byers is a reflection of this real-life bond.

3. The Jake Bongiovi Factor: Pact Broken!

Millie's engagement and subsequent marriage to Jake Bongiovi effectively "broke" the marriage pact much earlier than the agreed-upon age of 40. This news, which broke in 2023, was met with an outpouring of support from the entire Stranger Things ensemble, including Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, and Sadie Sink.

Noah Schnapp's reaction, however, was particularly heartfelt and public. As Millie's best friend, he was one of the first to comment, expressing his overwhelming excitement and happiness for the couple. His supportive response underscored the true nature of the pact—it was never meant to stop them from finding true love, but rather to guarantee a future together if they didn't.

The Final Chapter: Friendship Beyond the Upside Down

As the cast of Stranger Things prepares for the emotional finale of Season 5, the friendship between Millie and Noah is being highlighted as a defining legacy of the show. Their relationship has evolved from two young actors meeting on set as complete strangers to becoming inseparable confidantes in their early twenties.

4. The Sibling Dynamic: "Like My Brother"

Millie has frequently referred to Noah as "like my brother" and a "platonic soulmate." This term perfectly encapsulates the depth of their bond—a connection that is familial, supportive, and completely free of romantic pressure. They have witnessed each other's entire adolescence, from awkward teenage years to navigating global fame, which creates a level of trust and shared history few others can understand.

5. The Prank War and Viral Moments

Their friendship is also defined by their playful energy. The two are notorious for their on-set pranks and hilarious interviews, which often go viral on social media platforms like TikTok and Instagram. This lightheartedness provides a necessary balance to the intense, dramatic work they do on Stranger Things, where their characters, Eleven and Will Byers, often face immense emotional turmoil.

6. The Shared Experience of Stardom

The entire young cast, including the Duffer Brothers' main ensemble, shares a unique experience, but Millie and Noah, being the closest in age and having the most intertwined storylines early on, developed a particularly tight relationship. They have been each other's rock through the pressures of Hollywood, the scrutiny of the media, and the challenges of growing up in the public eye. Noah has consistently called Millie his "best friend."

7. The Future Beyond Hawkins: Supporting Each Other's New Ventures

Even as the show concludes, their professional paths are diverging, yet their support remains constant. Millie is now focusing on her production company, PCMA Productions, and her married life as Millie Bonnie Bongiovi, while Noah is balancing his acting career with his entrepreneurial endeavor, TBH. Their recent joint interviews, discussing the end of Stranger Things and Millie's new name, show that they are committed to supporting each other through every new phase of their lives, long after the Upside Down is closed forever.

The story of Millie Bobby Brown and Noah Schnapp is a powerful reminder that the most enduring relationships in Hollywood are often the platonic ones. While the famous "Marriage Pact" may be officially broken, the bond between these two generational talents—the one between Eleven and Will, and the one between two best friends—will undoubtedly continue to be one of the industry's most treasured connections for decades to come.
