Shirtless Justin Bieber startles Polish airport officials

In another strange incident during his current tour, Canadian pop sensation Justin Bieber startled Polish airport officials on Monday by parading through an airport shirtless.

After leaving his sold-out concert in the central Polish city of Lodz, the19-year-old pop singerremoved his shirt en route to the airport late Monday night.

Despite an outdoor temperature reported to be approximately -10C, Bieber proceeded shirtless into the airport, through security and to his gate. He dressed before boarding a private jet.

"He wasn't told to take off his clothes. He had no metal objects on him," an airport spokeswoman told Reuters. "He's quite skinny so I assume he was probably freezing."
