Natalie Portman wore a show-stopping look to the London premiere of Thor: Love and Thunder on Tuesday.

The Oscar winner, 41, stepped out on the red carpet in a stunning Dior red minidress which she paired with a matching floral headpiece.

The actress completed the look with a bold red lip, a colorful pink-and-purple smoky eye and matching, strappy heels.
