It's time for Justin Bieber to face the music... again.

Just as the pop star unveiled his new music video for "Confident," Bieber turned himself into Toronto police on Wednesday (January 29) in connection to an assault that took place last month, according to the Associated Press.

Bieber is accused of assaulting a limousine driver on the night of December 29 after attending a Toronto Maple Leafs game at the Air Canada Centre. At the time of the alleged incident, it was not clear whether it was Bieber or a member of his entourage who was directly involved.

The singer arrived at the Toronto airport just after 7:30 p.m. on Wednesday and immediately turned himself in. Bieber was born and raised in the nearby town of Stratford, Ontario.

Bieber is already facing his fair share of legal troubles. Heis set to be arraigned on February 14 in connection to his arrest last week under suspicion of DUI, resisting arrest and driving with an expired license. On Wednesday, the pop star pleaded not guilty to all charges.

Police said that Bieber admitted to smoking marijuana, drinking and taking prescription medication at the time of his arrest. According to a report from TMZ, Bieber's blood alcohol level was actually 0.014, falling below the 0.02 level that would be considered for an individual under 21 to be driving under the influence.

Earlier this month, Beverly Hills police raided Bieber's Calabassas home after he was accused of egging a neighbor's property. The alleged crime, while seemingly small, is being deemed a felony due to more than $20,000 worth of damage being inflicted on the neighbor's home.

In reaction to his latest string of hardships, more than 100,000 Americans have signed a petition asking the Obama administration to revoke Bieber's green card, deporting him back to Canada. According to the government's "We the People" platform, where the petition is posted, the White House must now respond to the request in "a timely fashion." (It's worth noting that DUIs and drag-racing are not deportable offenses.)
