All eyes are on Austin this weekend as the US Grand Prix takes over, with Lewis Hamilton knowing if results go his way, he'll be a world champion for a fourth time in his career.
If the Brit can obtain enough points over his Ferrari rival Sebastian Vettel, he will secure the Drivers' Championship this weekend, ending what has been a fascinating title race.
Three dreadful weeks for Ferrari and in particular Vettel have cost the team dearly, with a DNF in Shanghai following a crazy opening lap crash, a fourth place finish in Malaysia not enough, and then yet another DNF in Japan really ruining the German's season.
However, not all eyes have been on Hamilton and Vettel so far this weekend.
Yes the two finished first and second in qualifying, with Hamilton taking yet another pole to add to his already impressive tally, but another two drivers have also been in the spotlight following qualifying yesterday.
Sergio Perez of Force India and Kevin Magnussen of Haas have been making their own headlines due to an incident that took place during qualifying.
With Perez doing a fast lap, he was rightfully left fuming when Magnussen cut across him and blocked him off during a corner, costing the Force India driver dearly.
As expected, the 27-year-old was livid over his team radio as he couldn't get over what Magnussen was doing.
After being blocked by the Haas driver, Perez vented his frustrations over the radio, and did so in explicit fashion.
The onboard camera caught Perez saying: "Man, what is Magnussen doing? What the f*** is he doing? He's always the same man. It's unprofessional."
Watch the incident in the video below.
You can understand the driver's frustration because he was doing a fast lap, and after the race, Magnussen himself apologised to Perez as he was unaware of the situation, claiming he wasn't told Perez was doing a fast lap.
The Dane also admitted he expects a penalty for blocking Perez during the lap.
