Rosie Huntington-Whiteley showed off her summer body in a sexy video posted to Instagram.

The model dunned a barely-there red bikini while filming herself flaunting her toned physique in front of a mirror.

The 31-year-old shared several clips of herself putting the bikini on display. She opted for a simple updo and gold hoops to complete the beach look.

The British beauty welcomed her first child, a son, Jack, with husband Jason Statham in June 2017.
