Millie Bobby Brown is 20! The Stranger Things star holds hands with her fiancé Jake Bongiovi as they enjoy iced coffee in New York

Millie Bobby Brown's birthday started off casually.

The actress, who turned 20 on Monday, grabbed coffee with her fiancé Jake Bongiovi in ​​New York City.

The couple, who picked up a puppy from a Florida animal shelter so it could be placed in a forever home thanks to Joey's Millie friends, held hands as they took a peaceful stroll through Manhattan.

The Stranger Things star wore a navy blue sweater with pink, yellow and green stripes over a navy blue T-shirt.

She also wore pajama bottoms that resembled a patchwork, in various checked designs, with images of skulls and flames on them, and black sneakers.

The Enola Holmes star was makeup-free and wore her light brown hair in a loose bun, and accessorized with hoop earrings.

Jake, 21, wears a tan padded jacket over tan cargo pants.

The Sweethearts actor, the son of rocker Jon Bon Jovi, 61, wore a multi-colored sweater under his jacket and completed the look with white sneakers.

It seemed like both Millie and Jake preferred an iced coffee, despite the chilly 100-degree temperatures in Manhattan.

Fans quickly took to social media to wish the Godzilla: King of Monsters star a happy birthday.

'Congratulations Millie, I love you very much, you are a great actress. I hope you have a good time on this special day for you,” wrote one avid admirer.

'Congratulations Mills! May your life always be illuminated with happiness and may each new day bring with it infinite possibilities of love and success,” wished another.

Millie was expected to receive many more wishes during the day and night as she marked the big 2-0 with family and friends.
