What we love about Justin Bieber is that he's not afraid to speak his mind honestly all the time -- sometimes it's serious (like about his charity Pencils of Promise) and sometimes it's silly (like crazy backstage antics with his crew), but it's always 100% from his heart.
But on Saturday afternoon, Justin went on a "Random Twitter Hour" where he Tweeted a series of 26 messages that covered everything from his hero Chuck Norris to his fruit salad preferences.
Most fans thought it was just Justin being Justin with his crazy humor -- but when he ended it with a shocking Tweet addressing the rumors about Mariah Yeater, the woman who accused him of being the father of her child, it sparked controversy.
