Booba and Kaaris are arguably France's two most famous rappers. They've had a long-running feud that just boiled over into a massive brawl in Paris's Orly Airport's duty-free area.

The fight was so intense that the airport's west terminal was shut down for an hour and flights were delayed. 11 people were arrested.  Luckily, nobody was seriously injured.

In a hilariously French twist, at one point the combatants began beating each other with giant perfume bottles and other luxury items that they pulled from the duty-free shelves.

Booba was once a mentor to Kaaris, but their relationship took a bad turn about five years ago. This is the first time their beef has turned to violence.  Albeit very pleasant smelling violence.
