She always brings the heat.

Millie Bobby Brown, 21, shut down the red carpet Tuesday at a London screening of her Netflix film, “The Electric State,” oozing glamour in a dazzling red strapless gown.

Plucked from Wiederhoeft’s fall 2024 collection, the number was hand-embroidered with beads and had a lace-up corseted bodice.

The “Stranger Things” star allowed the gown to do all the heavy lifting, accessorizing with strappy wine-colored heels and ruby earrings.

Brown’s vibrant crimson lipstick perfectly complemented the gown, while her bold winged liner added a bit of edge to the red carpet moment.

She wore her platinum blond hair in soft, side-parted waves.

Last week, Brown made a splash at the film’s Madrid premiere, hitting the red carpet in the same sheer Giorgio Armani gown Gwyneth Paltrow wore at the “Shakespeare in Love” New York opening in 1998.

Eight years older than the actress herself, the archival dress — which Brown styled with a silk navy shawl, just like Paltrow — was embellished from top to bottom.

Brown shared the vintage look on her Instagram page, tagging @gwynethpaltrow in the caption.

The wellness enthusiast, 52, jumped into the comment section, gushing, “You wore it best!💙”

On Monday, Brown released an Instagram video clapping back at online bullies commenting on her appearance and how she’s aging.

“I want to take a moment to address something that I think is bigger than just me, something that affects every young woman who grows up under public scrutiny,” she began the lengthy video.

“I started in this industry when I was 10 years old. I grew up in front of the world, and for some reason, people can’t seem to grow with me.”

After reading headlines and naming journalists who have written about her appearance, Brown added, “The fact that adult writers are spending their time dissecting my face, my body, my choices, it’s disturbing.”

The actress concluded, “I refuse to apologize for growing up. I refuse to make myself smaller to fit the unrealistic expectations of people who can’t handle seeing a girl become a woman.”
