While performing his hit song, "Sorry," Bieber took a running start onto a stage covered in water from the massive downpour that is a signature element of his show. Bieber lost his footing and fell hard on his tailbone.
The incident was caught by a lot of fans videotaping the performance on their phones.
You have to hand it to the 22-year-old singer -- he recovered pretty well from what looked like a nasty spill.
However, he didn't recover nearly as gracefully as Lovato, who ended up falling after taking a small misstep while walking out on stage to greet her cheering fans at Thursday’s WE Day at The Forum in Inglewood, California.
While Bieber's water-soaked tumble made a bit more sense than Lovato's awkward stumble, the 23-year-old "Confident" singer made the best of an embarrassing situation by laughing and holding up her arms triumphantly as she lay on the floor.
