Justin Bieber Rocks London’s 02 Arena (PHOTOS)

Justin Bieber’s whirlwind, almost-riot-causing trek across the U.K. is still going strong, and the teen superstar is giving London a big old sweaty case of Bieber Fever.

Justin hit London’s 02 Arena on Monday night for the first of three concerts he’s set to perform this week. He’ll also be belting out his hits on Wednesday and Thursday, before heading to Manchester and Sheffield for three more shows.

Last week, hundreds of fans surrounded Bieber’s Liverpool hotel, prompting what police called a “possible riot situation” in the streets around Bieber’s pad. The star was holed up inside the hotel for hours, and his team was warned that he should not come out for fear it could spark a major incident. Watch a video from a fan outside in the melee:
