What do you do when you oversleep on Canadian Thanksgiving? Get naked, grab a guitar, and serenade your grandma. TMZ has photos (reportedly from October 2012) showing a nude Justin Bieber playing the guitar for his grandma. The lyrics of his song: “I loooove you grandmaaaa ... how are youuuu ... helloooo grandma.” His grandma reportedly loved the song, as did everyone else who was there to see his behind (and celebrate the holiday). As far as leaked naked pictures go, it could be much worse.
From peeing in a restaurant mop bucket to getting his pet monkey confiscated in Germany, here's a look at Justin Bieber's worst hits.
