Justin Bieber mixed it up Tuesday with the paparazzi in Paris and appeared to throw a punch during the fracas.
We're told Bieber and his crew tried to clear the photogs out of the way as they entered their hotel after dinner.
Check out Bieber -- inexplicably dressed in a camouflage jacket and pants with black leather sneakers -- his hand just below the neck of one photog ... another photo shows Bieber appearing to be in mid-punch.
