Millie Bobby Brown poses up with fiance Jake Bongiovi AND his famous dad Jon Bon Jovi at star-studded premiere of her Netflix film Damsel

Millie Bobby Brown caused up a storm with her fiancé Jake Bongiovi at the star-studded premiere of her Netflix film Damsel.

The project is a medieval fantasy starring Millie as a new bride who must fight for her survival when her in-laws try to sacrifice her to a dragon.

However, at the premiere, Millie was the picture of warmth in her relationship with her real lover and his real family.

She happily stuck out her leg as she got dressed with her 21-year-old boyfriend, who is just a year older than the Stranger Things alumna.

During the premiere, she also stood for a few group photos with Jake and his parents – Dorothea Hurley and none other than Jon Bon Jovi.

Millie arrived at the party in a sleeveless dress with a striking earth-tone design meant to resemble snakeskin.

Sporting a luxurious long hairstyle that was a striking contrast to her Stranger Things days, she balanced expertly on a sky-high pair of heels.

Meanwhile, Jake opted for a more classic style, wearing a black suit and tie and accessorizing with some burnt orange tones.

Jon was the epitome of rocker chic with his snow-white hair and black leather jacket, while Dorothea cut a youthful figure in a tight tan skirt.

During the red carpet portion of the event, Millie was also seen sharing a hug and boisterous laugh with her director Juan Carlos Fresnadillo.

She could also be seen hobnobbing with Bela Bajaria, the current Chief Content Officer at Damsel’s home streamer Netflix.

Millie stars in Damsel amid a formidable array of co-stars, including Robin Wright, who exuded a futuristic vibe in a silver color-blocked dress.

Oscar nominee Shohreh Aghdashloo, another member of the supporting cast, modeled a charcoal pantsuit that was cinched to emphasize her petite frame.
