There are many great, grandma-appropriate gifts in the world — it's pretty much why the gift basket and quilt industries exist — but if you're Justin Bieber's grandma, you're not going to receive any old present from your pride and joy.
The ever-thoughtful Justin decided that his grandma needed deserved an extra-special present, so he chose to serenade her and let her know just how much she means to him… while completely nude.
TMZ has the photos of Justin in all of his butt-baring glory (his junk is thoughtfully covered by his guitar), along with a creepy picture of him surprising his grandma, who looks a little less than pleased.
According to a source close to the newly nudist singer, the photos were taken when the Biebs was at home for Canadian Thanksgiving in October 2012.
Justin, who was staying at his grandmother's house, reportedly overslept on Thanksgiving morning, so as his way of making amends and getting a smile out of everyone, he stripped down to his birthday suit, grabbed his guitar, and busted out a song singing the praises of his grandmother.
His naked serenade reportedly did just the trick, although his family soon begged him to cover up.
Cue the sound of ten million Beliebers booking flights to Canada to have a serious talking to with her.
