Talk about pulled pork – CHRISTINA AGUILERA’s totally peeled off her pesky pounds in a headline-making weight loss, and a close pal finally whispered the secret behind “The Voice” coach’s newly slim ’n’ sexy frame…Reiki!

“It’s a Japanese method for healing the body, emotions, mind and spirit,” explained the source.

“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 master for private sessions three times a week.”

And Christina’s not alone: Reiki enthusiasts include sexy skinnies ANGELINA JOLIE, SANDRA BULLOCK, NICOLE KIDMAN and GWYNETH PALTROW.

And Reiki’s so easy to learn, says Christina, she now practices the ancient art on pals to relieve stress and keep them healthy.

(As BILLY RAY CYRUS might say: “If you’re achy breaky, try Reiki!”)
