Millie Bobby Brown looked like a different person as she debuted her 'mature' new look at the LA premiere of her new film The Electric State.
The 21-year-old actress looked stunning in her beaded metallic dress, featuring structured hips and a unique cape at the event, which was held at the Egyptian Theatre.
The Stranger Things star paired her look with an elegant and voluminous updo and a set of eye-catching thick bangs.
Millie's make-up was as striking as her outfit and hair as she opted for glam silver eyeshadow and black eyeliner.
The 21-year-old's husband Jake Bongiovi, 22, was also in attendance with Millie, and the loved-up couple even shared a sweet kiss for the cameras.
Her appearance at the premiere comes after she left fans in disbelief over her real age after looking a 'decade older' at the SAG Awards over the weekend.
Millie attended the awards on Sunday night, looking incredible in a silky peach slip dress and her newly bleached hair thrown into a 90s bombshell updo.
Although she may have looked amazing, fans were concerned that the British star looked 'too old' for her age, with users taking to X to share their thoughts on her grown-up look.
One user wrote: 'Literally had to double check it was her who turned 21 the other day and not 40,' whilst another penned: 'When did 21 going on 45 looks become fashionable?, and a third added: 'already looking like 30-year-old.'
However, in fairness to Millie she has been living well above her years, working in Hollywood since she was a child and quietly tying the knot with Jake at just 20 years old.
The couple said 'I do' in the US in 2020 before flying to Europe for a lavish wedding in Italy with all their family and friends.
Millie opted for a gown with a fitted corset-style bodice that flowed out into a long skirt. She added a lacy veil for an extra bridal touch.
Groom Jake also looked the part in a smart tux comprised of black trousers and a white jacket. He completed his wedding day look with a black bow tie
Millie didn't give away any information about the wedding in the caption to her post, simply writing: 'Forever and always, your wife.'
