Kate Beckinsale treated her social media followers on Thursday to a peek at her bikini body.

The 47-year-old actress shared a throwback video of herself strutting down a flight of stairs at an elegant residence. In the video, Beckinsale wears a strapless maroon bikini top and matching bottoms. She accessorizes the look in a pair of nude high heels and a flowy white beach cover up.

Her hair is also pulled back into a high bun and she's wearing sunglasses. Beckinsale's age-defying figure is on full display, and her fans made it known they appreciated the glimpse.

"This is a good example of what my mother would call 'walking as if one has bogged ones breeks.' And also of a short gay man silently falling into a cactus off camera. And also of exactly this time last year pre Covid. Buggering hell," Beckinsale wrote in her caption.
