Justin Bieber has turned himself in [1] to face an assault charge in Toronto, CNN reports. The singer traveled to Canada on Wednesday to be booked on the charge, which is reportedly in connection with an encounter with a limousine driver last month. This is the second arrest for Justin in a week — he was taken into custody last Thursday for a DUI and drag racing in Miami [2]. He was most recently seen in Panama, along with his rumored new girlfriend, Chantel Jeffries [3], riding ATVs and shooting a music video [4] on the beach. For what it's worth, Justin tweeted out the video's premiere [5] on YouTube just minutes before news of his arrest broke.
