'Four, 12, 16, 20 POUNDS of Epsom salt, in a bath,' she explained.

'Here we go, for real,' she explained while tossing the crystals into the bath as hot water filled the tub in her hotel room.

Looking back in the camera, she instructed interested fans to use 'water as hot as you can take it,' and advised a '30 minute soak the night before.

She also said best results come from drinking 'tons of water,' and getting 'off to bed early.'

The Shock and Awe star flashed a big smile at the camera before ending with 'see you tomorrow Met Ball.'

According to WebMD, the old fashioned remedy has a variety of uses, including skin exfoliation, relaxing tired muscles and detoxing the body.
