The 32-year-old singer made sure to maximise her workout as she headed to the gym in Thousand Oaks, California, on Wednesday, wearing a futuristic-looking 'sauna suit top'.
Sealing in body heat, the device is said to help wearers shed excess water during stretching and light exercising, while claiming to boost the benefits of workouts by keeping the muscles warm.
Proponents claim that as the body sweats to cool down the suit rids the body of toxins, while also increasing the metabolism and calorie-burning.
