According to TMZ, Justin was snapped in the nude at his Grandma's house in Toronto during Canadian Thanksgiving in October 2012.
The pictures show Bieber's bare butt and his front covered up with a guitar. He reportedly slept in and decided to sing to his grandma that morning naked... like Jenny did in the movie Forrest Gump.
