Lewis Hamilton won't be sharing a cold beverage with Esteban Gutierrez in Hungary.
The British driver found himself caught behind 21st placed Gutierrez on the 54th lap, and it very nearly cost him the race lead.
As Hamilton attempted to navigate his way around and lap the Mexican, Rosberg came within 0.6 seconds of his teammate.
When he finally managed to pass the 24-year-old, Hamilton gave him the old one-finger salute.
Gutierrez later took to Twitter to call out Hamilton, claiming the 31-year-old was "disrespectful".
Hamilton finished the race in first place, with a time of 1:40:30, while Gutierrez finished in 13th position.
