Justin Bieber takes a tumble onstage

Carly Rae Jepsen came to Justin Bieber's rescue after he took a tumble onstage at his concert in Canada on Tuesday (16Oct12).

The singers were performing their duet Beautiful for a sold-out crowd at the Credit Union Centre in Saskatoon when Bieber tripped while making his way down a set of stairs.

Fans gasped in horror as the Baby hitmaker fell and a loud thud could be heard throughout the arena as his microphone picked up the sound of his stumble.

Jepsen quickly rushed to spare Bieber's blushes, offering the star her hand and helping him back to his feet as they finished their track.
