Ferrari have released several glimpses into Hamilton's first day with the team, from being pictured in a sharp Ferramango suit, to meeting staff members alongside team principal Fred Vasseur and CEO Benedetto Vigna.
However, fans' patience was finally rewarded with a picture of Hamilton in a red racesuit following an official Ferrari release.
Hamilton finally took to the track on Wednesday at Ferrari's private circuit, Fiorano, where he got behind the steering wheel of the SF-23 as part of the Testing of Previous Cars (TPC) rule for 2025.
However, nothing could prepare the champion for the greeting from the Tifosi, who flocked to witness Hamilton's debut in their hundreds.
After he completed his first laps in a Ferrari car, Hamilton stepped out onto the track to wave to the fans who had gathered to watch the champion's historic test.
Hamilton was not alone, however, on his first day in a Ferrari, with his mother Carmen Larbalestier also attending to celebrate her son's team switch.
The champion's mother was spotted capturing the iconic moment with the Tifosi on her phone, the latest proud moment after decades of F1 success for her son.
Hamilton will make his full Ferrari debut in the 2025 car at pre-season testing in Bahrain from February 26, and will compete in his first race with the team on March 16 for the Australian Grand Prix.
