Justin Bieber Gets Totally Nude In Private Serenade For #1 Fan!

j bieber thumbWe knew it was only a matter of time before pop diva Justin Bieber had a massive wardrobe malfunction. We just didn’t expect it to be so calculated!

TMZ has obtained photos of the tween star brazenly walking around his home buck naked and thumping his junk on the backside of a guitar for one of his most diehard and privileged female superfans—his grandmother! What a lucky lady!

Sources say Bieber spent last Thanksgiving at Grandma Biebs’ house in Toronto, where he slept in a little too late on Thanksgiving morning. Grandma Biebs got a little agitated, so the pop star descended upon the kitchen, where he serenaded his grandmother and guests in his birthday suit. Apparently in Canada, this is an acceptable way to apologize to your grandmother.

Grandma Biebs reportedly thought the impromptu performance was funny, but “begged” her naked grandson to put his diaper back on.
