The 19-year-old singer was departing from Wladyslaw Reymont Airport in Lodz, Poland when he -- for unknown reasons -- removed his shirt while undergoing a security check.
According to reports, the "Beauty and a Beat" singer waited patiently at the check point while flaunting his naked upper-body and his usual saggy pants.
Last month, Beiber was photographed half naked in a couple of similarly unnecessary opportunities. Enter the time he shirtlessly returned to his hotel in London on the night he celebrated his 19th birthday, and the day he shared a shirtless photo of himself from a hospital bed.
