Madonna has been hard at work preparing for her "Madonna: The MDNA Tour" event June 22.
In the meantime, she has been working out. She posted her first Instagram video of her shaking her 54-year-old figure.
She captioned the post, "Hard candy booty pop up class! Getting ready in the bathroom! NY here I come!"
Earlier today, Justin Bieber took advantage of the new video feature of Instagram, shirtless and giggling.
