Washington DC [US], February 20 (ANI): A sweet birthday post, a throwback pic, and a few heartwarming words, sometimes that's all it takes to remind fans why the friendship between Millie Bobby Brown and Noah Schnapp is one of the most beloved off-screen bonds to come out of 'Stranger Things.'

Milllie turned 22 on Thursday, February 19, and her longtime best friend Noah made sure the day didn't go by without a public dose of affection for her Stranger Things co-star. Taking to his Instagram Story, Schnapp shared a black-and-white photo of the two sitting together in a car.

Along with the picture, the actor penned a personal note that spoke volumes about their years-long friendship. Calling Millie his 'longest friend,' Noah wrote that he would be 'lost' without her and wished her happiness

Calling her his 'superhero twin,', the actor wrote, 'Happy birthday to my longest friend. Mil, I'd be lost without you. Here's to so much love and happiness in your Taylor year: Us against the world, my superhero twin, in every universe.'

This isn't the first time Schnapp has marked Millie's birthday in a special way. Back in 2023, when Millie turned 19, he shared a carousel of photos chronicling their friendship through the years. The post included everything from cozy black-and-white shots to candid moments of them eating together, childhood throwbacks with French fries in hand, and even a snapshot of the two asleep next to each other on a plane.

Noah Schnapp and Millie Bobby Brown quickly became close friends when they met on the set of 'Stranger Things' in 2015. The two instantly bonded while filming the first season of the show. Over the years, their friendship has remained strong, with both describing it as a 'family-like' connection. (ANI)
