He's currently Down Under to attend a five day 'Christian' Hillsong convention after recently getting involved with the religion。
While taking a dip in the chilly salt waters at Bondi's Icebergs pool on Monday, the global superstar revealed that he'd been undergoing the ancient Chinese 'cupping' practice, revealing several large yellow bruises on his tattooed torso。
In 2014, the Baby singer was baptised by Hillsong Church Pastor Carl Lentz。
Justin joins a long line of clean living celebrities who practise cupping, including Victoria Beckham, Jennifer Aniston and Gwyneth Paltrow。
Dating back 5,000 years, the therapy is a form of acupuncture, and is based on the idea that suction from the cups draws the skin up and mobilises blood and energy around the body。
Perhaps feeling the blood pumping through his veins, or just the sensation of icy cold water on his body, Justin looked exhilarated as he emerged from the ocean pool on Monday。
Strutting solo poolside, he grinned form ear-to-ear before raising his arms and fist-pumping the sky。
