Christina Aguilera's weight loss is down to Reiki sessions.
The 'Fighter' singer has recently unveiled a new, much slimmer figure after losing 30lbs and credits her new body to practicing the spiritual healing technique.
A source told the National Enquirer: "It's a Japanese method for healing the body, emotions, mind and spirit.
Christina also credits a low-carb diet and yoga workouts for her new look, but Reiki puts her mind in a good place and gives her the discipline to eat healthy and maintain weight loss.
She sees a Reiki mater for private sessions three times a week." 'The Voice' USA judge, 32, has previously said she feels "refreshed" by her weight loss because she's been able to spend more time with her five-year-old son Max.
She said: "I got to have, finally, a break and spend some time with my son ... being able to breathe and have time away outside of the camera and get to the nitty-gritty of all things real and personal [allowed me to come] back refreshed."
