Justin Bieber was full of surprises at the August 7 Teen Choice Awards. The Teen Dream showed up sporting, among other bizarre things, a sparse but clearly discernible growth of upper lip fuzz. This wasn't Biebs' first attempt at starting a stache. What is intriguing about his sudden decision to cultivate some facial hair is the timing. Is JB growing a mustache to impress Selena Gomez? Or are his motivations more complicated?So much for the past. What about the present? Has JB decided to seriously "commit to growing a mustache?" And if so, why now? Is it to show Selena Gomez that he can? Is it because of his reported fears that someday, his increasingly famous singer/actress girlfriend will dump him for an older guy, like her former crush Shia LaBeouf.
