yes he is...you can see all of the info at bieberzone.tk and it says bio and his mom wrote all of that kind of stuff, like he is left handed he played hockey, and all hat stuff....HE IS HOOOTTTTTTEEEEEEEEERRRRRRRR THAN THE SUN!!! HAHA...LUVALWAYSJUSTIN!!!
yes, Justin is left handed it is easy to tell. when he plays the guitar he has the guitar neck in his left hand and strumming using his right hand. this is because left handers do most of the work using the left hand (which it takes more work to change chords than it does to move your arm up and down) but the right handers do the opposite. hope you found this useful! :P
yes hes left handed because wen he was learning guitar he only had a right handed guitar in his house it was tough for him to learn the strings upside down and plus ive seen him sign a autograph with his left hand
