The moment a young boy ruined a pregnant woman's gender reveal surprise has gone viral after footage captured the soul-crushing moment on camera.
The expecting mother from Sydney was preparing to find out the sex of her unborn baby, carrying a balloon that would soon reveal the gender.
However, the surprise turned sour when the naughty boy popped the balloon prematurely before the reveal party.
