PREVIEW

While performing her Hit Me Hard and Soft show at Madison Square Garden in New York City last Friday night, the Bad Guy singer tripped while walking down a set of stairs as she exited the stage. Taking to her Instagram Stories on Tuesday, Billie re-posted a fan video of the moment and wrote, "Billie falling down the stairs at msg (sic).". She also shared a close-up photo of a large purple bruise on her left thigh. "But literally," the 22-year-old wrote over the snap.
