Millie Bobby Brown poses with her fiancé Jake Bongiovi AND his famous father Jon Bon Jovi at the star-studded premiere of her Netflix film Damsel

Millie Bobby Brown turned heads 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 to survive when her in-laws attempt 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 stretched her leg as she got cozy with her 21-year-old boyfriend, who is just a year older than the Stranger Things alum.

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

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

She sported a luxuriously long hairstyle that was a striking contrast to her Stranger Things days and expertly balanced on a pair of towering heels.

Meanwhile, Jake opted for a more classic style, appearing in a black suit and black tie and accessorizing it with dark orange sunglasses.

Jon embodied the epitome of rocker chic with his snow-white hair and black leather jacket, while Dorothea cut a youthful figure in an elegant brown skirt.

During the event's red carpet, Millie was also seen hugging her director Juan Carlos Fresnadillo and laughing out loud.

She was also seen fooling around with Bela Bajaria, the current chief content officer at Damsels Home streamer Netflix.

Millie stars in Damsel among an impressive array of co-stars, including Robin Wright, who exuded an air of futurism in a silver, color-blocked dress.

Oscar nominee Shohreh Aghdashloo, another member of the supporting cast, wore a charcoal gray pantsuit that was form-fitting to accentuate her petite figure.
