Millie Bobby Brown cuts a casual figure in a tracksuit as she steps out with Jake Bongiovi in Milan 

Millie Bobby Brown put on a crazy display when she arrived in Milan with fiancé Jake Bongiovi on Friday.

The actress donned a comfy purple tracksuit from Rotate and grinned at Jake as he strolled through Milan Malpensa Airport and a throng of fans.

She also made the odd decision to put a box on her head with a face on it as she prepared for her Stranger Day meet and greet with fans at the city’s Alcatraz.

The beauty looked lovingly at her betrothed as they stepped out together.

Millie wore her light brown locks in an updo and later changed into a white blazer and skirt for her event.

She also put on a pair of black and silver boots, which made her taller by inches.

It comes after Millie flashed her gorgeous engagement ring on Instagram earlier this month.

The Stranger Things star, 19, took to social media to share how she’s set to launch a new coffee range through her beauty brand Florence By Mills, which she said was a venture she’s been dreaming of ever since [she] can remember.’

After teasing the new business, which will add to her £11 million acting fortune, Millie blew a kiss to the camera showing off her ring, which is estimated to have cost 20-year-old Jake a whopping £120,000.

While best known for her role as Eleven in Netflix’s supernatural hit Stranger Things, Millie is also a savvy businesswoman thanks to her brand which also has a makeup line and future fashion collection.

Millie emphasized her natural beauty in the video as she wore light makeup and styled her dark brown locks into a sleek look. The actress completed her ensemble with dangling earrings and a matching necklace.

In her video’s caption, Millie wrote, “If you know me, you know I can’t start my day without my morning coffee! I am so excited to finally be able to share Florence By Mills Coffee with all of you!

‘We had so much fun making and tasting the delicious coffee and can’t wait for you all to try the launch collection!

Be sure to follow the @florencebymillscoffee account for all exclusive updates and sneak peeks! I look forward to all our coffee talks together! Xoxo mills.’

Millie announced her engagement with a post showing off her shimmering rock in a monochromatic photo.

She wrote in the caption, “I’ve loved you for three summers now, baby, I want them all.”

While Jake also shared an announcement post on his own page, he simply wrote “forever” alongside two snaps of the couple.

To celebrate the joyous news, the lovelorn couple took part in a beach photo shoot – with Millie dressed in a crochet dress while Jake donned a cream colored polo shirt.

The announcement confirms some speculation that has been circulating on social media in recent weeks, after she glimpsed the ring in a recent post.

Millie posed behind the wheel of a convertible in a photo last month, looking away from the camera and raising her hand, revealing the prominent diamond ring on her finger.

While she also sparked rumors in August when she wore a gold diamond ring on her wedding finger during a PDA-packed outing.

Sharing that they had spent “three summers” together in the announcement post, it comes after the actress recently bragged the dirt about how she and Jake met.

Millie explained that they connected on Instagram and became friends through the platform, before romance ensued.

Answering the most common questions about her on the internet, she said, “We met on Instagram. And we were friends for a while, so what can I say?’

She introduced Jake to her 62.7 million followers in June 2021 with a cute photo of him on Instagram, but it wasn’t until she posted a photo of him planting a kiss on her cheek that they were “Instagram official.”

Millie called Jake her “partner for life,” in a gushing post in which she shared a series of photos of the couple in January 2023.
