Nico Hulkenberg and Kevin Magnussen started the half-term break in a war of words with the latter telling the Renault driver to “suck my b****, honey” when they met in parc ferme after the Hungarian Grand Prix.
The disagreement started when Hulkenberg attempted to pass the Haas driver following a slow pitstop that left him in 12th but he the Renault was forced onto the grass, an action that left Magnussen serving a five-second time penalty.
While they were fulfilling their media commitments, Hulkenberg approached the Dane to sarcastically congratulate him on being the “most unsporting driver” on the track.
In his post race interview, the German driver told NBC: "I congratulated him for being the most unsporting driver of the whole grid once again. When it comes to racing, he's just nasty. Hard defending is fine but when he does this, it's just ruthless and sending people into the wall.

"What he did there, opening up the steering, making me run wide, it's just being an a***hole basically. We had really nice words, he said [suck my b****], that was his return, so it's quite interesting with him."
Hulkenberg added that he would talk to the the race stewards about it: "I'll go and speak to Charlie [Whiting]. I hear he got a bit of a penalty, five seconds, but in his mind he won't care about that too much."
The German driver had already been involved in an incident with Magnussen’s teammate Romain Grosjean earlier in the day when the Frenchman was forced wide at Turn 2 during the opening lap of the race.
At the time, Magnussen could be heard saying over the radio: "If you can do what Hulkenberg did to Romain, then it's going to be a dirty race."
Following the driver’s confrontation, Haas team boss Gunther Steiner got involved and called the Renault driver a “bully” and admitted that he had no problem with the words Magnussen had used.
He said: "It's the right way to say it. Why would he say anything else? He got a penalty, if he [Hulkenberg] thinks he [Magnussen] needs more [of a penalty], then he [Hulkenberg] needs to look at his Turn 1 incident.
"Is it sporting to run into Romain? [Hulkenberg] is a bully and he got away a long time with it and maybe now it's time that somebody stands up to him.
"He's a good driver, he doesn't need to be like this."
The Haas boss concluded that he would speak to the German driver when F1 restarts after the summer break.
