Video: Justin Bieber Tumbles on Stairs During Show With Carly Rae Jepsen

When performing 'Beautiful' in Saskatchewan, Canada, Bieber accidentally missed his step and fell on a stairway but managed to finish the set as if the incident never happened.

Another mishap happened during Justin Bieber's "Believe" tour. After recently puking on stage in Arizona and having his laptop stolen while performing in Washington, Bieber had a major fall on the stage when delivering a duet with his tourmate Carly Rae Jepsen in Saskatchewan, Canada on Wednesday night, October 17.

Rocking casual white shirt and leather pants paired with a round hat, the Biebs along with the "Call Me Maybe" hitmaker delivered a song called "Beautiful". Near the end of the performance, the "Girlfriend" hitmaker walked down the stairs on the stage alongside his duet partner, but unlucky for him, he missed a step and lost his balance before falling back two steps.

Jepsen spontaneously grabbed his arm to keep him steady. Still, the boyfriend of Selena Gomez managed to show his professionalism and continued singing and finishing the love song as if the incident never happened.

Bieber's "Believe" tour has kicked off since last September and is expected to continue until next year. After performing in Saskatchewan, he will greet his fans in Winnipeg and Minneapolis on October 18 and 20 respectively. The Canadian popstar is scheduled to jump into the European leg of his tour around February 2013.
