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.
Biebs has been a busy boy in Paree ... dining with Kendall Jenner and later partying with Kendall, Kim Kardashian, Kris Jenner, Paris Hilton and GF Selena Gomez ... but avoiding Miranda Kerr like Ebola.
