Britney Spears flashed her hot bikini body on Instagram while relaxing on the beach in Hawaii.

“Another great day!” Britney gushed in the Instagram video as she lied on a gorgeous sandy beach in a tiny pink bikini.

Spears has been enjoying a much-needed vacation after dropping her ninth album, Glory.

Included on the album is the track Make Me, featuring rapper G-Eazy.

“Glory” is Britney’s first music album since 2013’s Britney Jean.

Britney has been having a great summer, working hard in Las Vegas between several family trips to Hawaii.

Spears looks fitter than ever, and has been showcasing her buff bikini body on Instagram recently.

Another great day!

Britney’s weight loss and bikini fitness secrets are a low carb diet, yoga workouts and cardio exercise, Celebrity Health Fitness reported.

The pop princess said her body changed a lot after two pregnancies, but a low-carb diet combined with consistent exercise keeps her fit and controls her weight.

Spears usually runs on the treadmill or the elliptical trainer at home to torch calories and keep her thighs and buttocks firm.

Britney, who loves sweets and starchy foods like french fries, typically follows a low-carb diet, but admits she has cheat days.

Low carb, high-fat diets like the ketogenic and Atkins diets fuel rapid weight loss by inducing the body to burn fat for fuel, said obesity expert Maria Emmerich, author of Quick and Easy Ketogenic Cooking.

Health guru Martina Slajerova agrees. Low carb, high-fat diets keep blood sugar stable, suppress appetite and prevent depression, said Slajerova, the author of The KetoDiet Cookbook.

The 5-foot-2 Kim, who weighed 200 pounds while pregnant, now weighs 120 pounds and has never felt better.

At 34, Britney Spears has bounced back from her turbulent 20s, when she was forcibly hospitalized and placed on suicide watch. She’s now healthier and happier than ever.
