Madonna posted this video of herself dancing on social media to celebrate the 40th anniversary of her debut album, which included hits like Borderline, Holiday, Lucky Star, and more! She certainly seems to be on the mend after being in the hospital earlier this month with a serious infection. No word yet on when her Madison Square Garden tour dates will be rescheduled, but she still plans to start her Celebration Tour internationally in October.
