How nice of Justin Bieber to offer those thirsty photographers a drink!

At least, that's what we'll assume he was doing when he chucked a plastic water bottle in the paparazzi's direction on his way out of a store in Miami yesterday.

No further drama occurred, it not being one of those days for the Biebs, but the 19-year-old is still probably pretty lucky that no cops were around to witness his mild outburst.

According to state law, there's a $50 fine for littering, plus a judge could make him pick up trash or "perform other labor commensurate with the offense committed."

It's unclear what provoked the reaction, other than the paparazzi's general presence, but perhaps a curious shutterbug asked how Bieber was feeling after being shut out of the Grammy nominations.

But it's the paps in Washington, D.C., who better duck now—Bieber, who also just announced a slew of summer 2013 dates on his Believe World Tour, was in town tonight to headline Hot 99.5's Jingle Ball concert.
