Justin Bieber definitely knows how to let it all hang out.

He gets into bloody fights, puts fans’ cell phones down his pants, and even gets wild while in the Hamptons! Now, JB has gone to another level: getting naked in public!

During his trip to Canada for Thanksgiving last year, Bieber decided to pull a fast one on his family and surprise them with a beautiful serenade, while being butt ass naked!

He was reenacting a scene from the movie, Forrest Gump  when Jenny played her guitar for Forrest, except Bieber replaced her words with,

“I Loooove you grandmaaaa … how are youuuu … helloooo grandma.”

Cute!

Of course, Granny thought it was funny! However, according to TMZ, she begged the pop star to get back in his room to put some damn clothes on.

TMZ  has these priceless pictures that’ll definitely brighten up your Monday morning!
