Beyonce Gives Fans the Full Monty

Less than a month after a spectacular on stage fall down a flight of stairs, Beyonce was singing in Toronto when the forces of nature aligned to blow up Beyonce's dress -- revealing her breasts to the crowd ... and she wasn't wearing a bra! Ring the alarm!

Beyonce, much like she did after taking a nosedive, never missed a beat and kept right on going -- though she did hang on to her dress to ensure that it didn't happen again. A few minutes too late!
