Justin Bieber Shirtless In Polish Airport: Singer Strips As Police Investigate Him For Battery [PHOTO]

Justin Bieber seems eager to prove that no climate is too cold for him to go shirtless. Just weeks after Olivia Wilde urged the singer to put some more clothing on, the 19-year-old pop star wowed paparazzi by walking half-naked through a Polish airport after performing at a sold-out concert.

According to Reuters, Bieber removed his shirt in his car outside of Wladyslaw Reymont Airport in Lodz late on Monday night despite near-freezing temperatures. The publication reported that it was 14F outside when Bieber walked “topless” into the building, passing through a security checkpoint wearing only his low-slung pants and putting his shirt back on as he was boarding his plane.

While Justin’s security team didn’t appear to be surprised by his lack of clothing, airport officials said they were puzzled.

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

Despite winter temperatures, Bieber has been photographed more and more recently without his shirt on. For his 19th birthday on March 1, the singer partied in London where he was spotted taking a shirtless nighttime stroll through the city, which the Daily Mail noted was “somewhat bizarre” given the “freezing winter weather that was gripping the capital.”

Bieber has also taken to tweeting shirtless pictures of himself to his fans, whether working out, hanging out backstage, sunbathing on the beach, or even lying in bed.

Bieber’s latest stripping stunt is only the latest of bizarre reports about the singer. On Tuesday TMZ reported that one of his neighbors accused him of physical battery.

Steve Whitmore, a spokesman for the Los Angeles County Sheriff's Office, said that the neighbor told deputies Bieber had made physical contact with him. The accuser filed a battery report, in which he claimed that Bieber had also threatened him. Sources who spoke to the gossip site claimed that the altercation had taken place over a noise complaint. The Sheriff’s department is reportedly investigating the matter.

Bieber is expected to perform in Germany and Finland next month, and recently announced he will also be visiting Russia.
