The 21-year-old beauty took to Twitter to show off her freckles in a stunning makeup-free photo as she spent some time relaxing by the pool.
She also shared a sexy snap of her fit bikini body soaking up the sun with the caption, "Summertime."
The "Neon Lights" singer is looking hotter than ever these days. So, how does the former Disney darling stay in shape?
According to her trainer, Joey Rubino, Demi enjoys "Bootcamp style workouts that consist of very little down time, lighter weights but a lot of reps - keeping the heart rate high and working up a good sweat. Workouts like these offer variety and a chance to have some fun while working hard and getting great results."
Rubino also said that the songstress is not on a diet, but she follows a healthy nutirition plan. "I have Demi juicing daily as well as eating a hearty breakfast and all meals consisting of protein and vegetables," he told Perez Hilton. "Since tour schedule can be crazy, it's important to eat regularly and include as much of a variety of whole foods as we can."
Her diet and fitness plans are paying off!
