Aston Martin driver Alonso finished P11 at last weekend's Italian GPwith a decent drive, just missing out on some points.
However, on Tuesday, the 42-year-old had to respond to a social media post claiming that his new Aston Martin Valkyrie supercar had broken down.
His reply was in Spanish but translated to 'Gaining credibility' with the hashtag 'distantsources' along with a lot of laughing emojis as he appeared to mock the author for their lack of credibility and use of a false source.

Following on from his reply the two-time world champion revealed that his Valkyrie supercar, designed by Adrian Newey, had arrived in a post on X today.
It read: "The day has arrived! I am a proud owner of the best road legal car on the planet. What a privilege to work for this brand."
With F1 heading to Baku next for the Azerbaijan Grand Prix, Alonso will be hoping that his Aston Martin doesn't break down in the race as he looks to score some more points.
