Pop star Madonna has reportedly purchased oxygen machines for each one of her homes, to help her boost her energy levels and combat jet-lag.
The queen of pop originally bought the machines to give herself oxygen facials, which help her maintain what she considers a porcelain doll-like complexion.
After pampering herself with the facials for over a year, she is rumored to have discovered other uses for the machine.
She explains in an interview, "You can also take the oxygen machine and inhale if you're feeling really tired or jet-lagged, which is one of the reasons I have them at home. You just lie down for 10 minutes and put it in your nose. They are really great."
