The singer had his guns – as well as his entire upper torso and most of his underwear – on full display while going through airport security in Lodz, Poland, on Monday.
Maybe he was wearing a metal top?
Bieber, 19, was in the Polish city – where the high was a chilly 30 degrees Fahrenheit – for the latest stop on his Believe tour.
"CRAZY SHOW!! Thank u POLAND!" he Tweeted late Monday.
This recent display of Bieber's body comes after a similar moment in London, where Bieber had a tough week that included a trip to the hospital, a late arrival to his show at the O2 Arena and a scuffle with paparazzi.
Get ready, Germany, he's heading your way next.
