Singer slips during a concert in Brazil

Beyoncé Knowles almost landed on her bum as she performed a gig last week.

The singer slipped while she belted out hit track Irreplaceable in Brazil.

Quick-thinking Beyoncé even managed to make the tumble look like a dance move.

Beyoncé, 28, famously fell down a set of stairs during a concert in Orlando in 2007.
