Justin Bieber is under fire yet again after allegedly spitting over a Toronto hotel balcony while a throng of his fans waited below.

The 19-year-old, currently in the city for two dates on his Believe tour, was photographed with friends standing on a balcony at the ritzy Hazelton Hotel when he appeared to gather and spit over the rail.

The same day, Bieber posted a video to Instagram showing the gathering fans below.

The incident has already inspired worldwide media coverage, with the U.K. tabloid the Sun devising the creative headline: 'Justin Bieber in new spit storm.'

This isn't the first time that Bieber, known for hits like Baby and Boyfriend, has raised controversy this month.

In early July, he personally apologized to Bill Clinton after a video was released that captured Bieber urinating into a restaurant mop bucket and later using expletives to dismiss a framed picture of the former U.S. president.

It's not even among the first controversies specifically relating to the Stratford, Ont., heartthrob's saliva.

Recently, he's reportedly been accused of spitting at a neighbour, a DJ and a woman at a gym.

Bieber plays the second of two Toronto shows on Friday at the Air Canada Centre.
