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.
