Most F1 drivers are able to keep their personal rivalries behind closed doors, but one spilled out live on TV after the Hungarian Grand Prix.
Haas driver Kevin Magnussen was giving an interview to a Norwegian broadcaster when he was approached by Renault's Nico Hulkenberg, who was clearly unhappy.
Hulkenberg had been forced to retire from the race one lap before the end, following an incident when he was forced off the track while looking to overtake Magnussen.
The German driver tapped the Danish racer on the shoulder as he was speaking and told him he was "once again, the most unsporting driver", with a thumbs up.
Magnussen was entirely unapologetic, telling Hulkenberg to "suck my b****, honey", before his rival was led away by a Renault official.
