Justin Bieber's naked tushy is no way to begin the week, people. In fact, the sight of Biebs' buns has us desperate to crawl back into bed, pull the covers over our heads and not emerge until his pop idol reign has ended (so, not too long from now). But reality must be faced, so here we go: TMZ has obtained images of a butt-naked Bieber, 19, holding a guitar in front of his dangly parts while serenading his grandma (yes, GRANDMA) on Canadian Thanksgiving back in October 2012.
Seems Canadian Thanksgiving traditions are different from American ones, although both apparently feature giblets and white meat.
According to TMZ, the incident took place after Justin overslept while celebrating the holiday at his grandmother's Toronto home. He woke up to the sounds of friends and family, but instead of merely showing off his underpants in his de rigueur droopy pants, he decided to prank them by strumming in the altogether. Bieber grabbed his guitar and strolled up to the matriarch while serenading her with such lines as, "I loooove you, Grandmaaaa ... How are youuuu? ... Helloooo, Grandma."
TMZ says Bieber's MeeMaw and the other relatives thought his buff stunt was kinda funny, but that his granny "begged" him to return to his room and get dressed.
It's unclear how TMZ came into possession of the nude prank pics.
