Justin Bieber fell hard on Thursday night.

The "Sorry" singer -- who got back up and went on with the show -- didn't seem fazed by the tumble when he tweeted after the concert. "Great show tonight. #PurposeTour," he wrote.

This is the second time in three months that Bieber has fallen during a performance. In April, while performing in Kansas City, Missouri, he lost his footing and dropped down on his tailbone while getting a running start through water that covered the stage from the massive downpour that is a signature element of the show. Just like his most recent whoops, Bieber recovered and went on with the show.

The singer's stage dive comes just one week after cameras caught him getting into an altercationwith a man at a Cleveland, Ohio hotel. Following the incident a source told ET that those close to Bieber are concerned for him.

"People around Justin are nervous about him and worry that he could have a breakdown," the source said. "He feels like people forget that he is a human being and needs privacy. Him writing those social posts about the 'no photos etc…,' that is him just being overwhelmed. It wasn't intended to make people think he is a snotty pop star, but it's definitely reflective of what he is going through right now. During his time off, he has been trying to be as normal as possible and trying to be super low-key about everything."
