Justin Bieber's performance canceled over safety concerns for 'enormous crowd'

Australians had one shot to see Bieber sing about his "Baby," but all hopes were dashed when a performance scheduled for Monday (April 26 -- yep, they're a day ahead over there) for morning show Sunrise Channel 7 was forced to cancel.

The reason? Concerns over the safety of the fanatical fans. Reports say the massive crowd, including folks who had camped out since Sunday night, was getting out of control.
