Millie Bobby Brown turned 20 on Monday, Feb. 19, and she certainly celebrated in style.

The Netflix star shared a few candid images from her small birthday party on Instagram, looking cool and confident in her eye-catching ensemble.

For the event, Brown rocked an all-white strapless mini dress, some silver jewelry, and added a bit of elegance by styling her hair in a chic updo. Also featured in the pictures was her 21-year-old fiancé, Jake Bongiovi, and a few of her closest friends, all of whom were decked out in head-to-toe white ensembles–have we caught on to her theme?

"the best time 🤍," she simply captioned the Feb. 21 upload, also tagging the venue, the Cathédrale Restaurant in New York City.

Fans were obsessed with not only her look but also the way she documented the festivities, as they shared their love for the glimpse inside her life and celebrated her big day in the comments.

"Your photo dumps are EVERYTHING," one top-liked comment read.

"Millie has been eating [it up] lately😭," a second shared. "everything she posts eatsss."

"happy birthday beauty 🤍," another gushed.

"20 years of the greatest actress of all time, congratulations my friend, you are incredible🎂🫶🏻," someone else declared.

Even Paris Hilton replied to the post, which apparently left her speechless, as she commented just a heart-eye emoji.

While her followers were undoubtedly impressed by Brown's style, they were also pretty adamant that something was missing–one of her Stranger Things co-stars.

"Millie, I miss the photos of you and Noah [Schnapp] every year when you have a birthday 😭😭😭😭😭😭 I need this," one admitted.

"WHERE IS NOAH 😭😭😭😭 I MISS U TOGETHER 😭😭😭," another confessed.

As for Schnapp's absence, the British actress didn't explain it. Hopefully, for fans, the entire cast will be by her side when she and Bongiovi finally tie the knot.
