The pop star showed off her pert bottom and perfect figure by wearing only a pair of white bikini briefs in the image, which pictures her staring at the scenery from a boat.

The 34-year-old captioned the Instagram shot: "Still dreaming a mile a minute."

The cheeky photo was taken just days after Britney unleashed the steamy music video for her latest single Make Me and then revealed the title and release date of her ninth album, Glory.
