It seems like only yesterday that Justin Bieber was charming us with his puppy love anthem, "Baby". Now, the pop sensation is getting more mature by wearing drop crotch pants, developing perfumes, and doing something that all of us do when we reach adulthood: Expose our abs and grab our crotches. The Biebs did the aforementioned anthem whilst performing at the Jingle Ball in Washington. There's nothing like a good ol' crotch grab and ab flash to celebrate the holidays, right?
