Britney Spears Dances on the Beach in an Tiny Orange Bikini in Latest Sexy Instagram Video

By
If there's anything Britney Spears loves as much as Instagramming an inspirational quote or stock photo of a children's tea set, it's Instagramming a sexy video of herself dancing around wearing nearly nothing.
The latest? The 34-year-old singer shaking it on the beach to Mark Ronson and Mystikal's "Feel Right" in an orange bikini. She wrote alongside the snap, "Happy Friday!"

In the short clip, Spears strikes a sexy pose against a rock wall, twirls around, seemingly breaks laughing, goes back to the rock wall where she poses again, shakes her hair, and then sticks her tongue out toward the camera.
In a follow-up post, the pop star shared a shot of the ocean and captioned it, "Starting the weekend off right," adding a wave emoji for good measure.

Spears wore even less when she posed for Mario Testino's iconic Towel Series. The photographer -- who was behind the camera for the "Toxic" singer's new V Magazine cover shoot -- captured the mom of two looking sultrily over her bare shoulder.
