JUSTIN BIEBER GOES STARK NAKED DURING BIZZARE PRANK ON HIS GRANDMA

This was supposed to be joke but I don't see the humor in it. Justin Bieber shocked his family when he played a bizarre nude prank at his grandmother's house in Toronto during Canadian Thanksgiving last year October. 

According to TMZ, the 19-year-old who was staying at his grandmother's home in Toronto when the incident happened, had over slept on Thanksgiving morning. When he woke up, he heard family and friends stirring around the house and decided to play a prank on the them by grabbing his guitar and playing it naked.  

The pop star went right up to his grandmother, Diane Dale, and started singing: 'I Loooove you grandmaaaa ... how are youuuu ... helloooo grandma', with nothing on safe for a guitar covering his private parts, as he a serenaded his granny. While his family and friends were laughing, his giggling granny begged him to get back in his room to put some clothes on. See the photos after the cut...
