It will be the end of a partnership that has seen eight constructors' titles accumulated in a highly-successful period that has also helped Hamilton boost his drivers' championship count from one to seven.
Throughout their record-breaking partnership, Mercedes have bought into the Hamilton 'brand', with the 39-year-old allowed to express his charming off-track personality to his adoring fans.

Roscoe Hamilton's barking birthday celebration
One way in which Hamilton has appealed to fans across his dominant spell in F1 has been through his dog Roscoe, who even has his own social media page.
Roscoe Hamilton is often seen during F1 race weekends, with Hamilton walking the Bulldog around the paddock.
Other F1 stars have since sought to emulate Roscoe and Hamilton's fame, with future team-mate Charles Leclerc bringing his adorable puppy Leo to various race weekends this season, and Pierre Gasly's equally adorable dog Simba also making an appearance.

Now, Roscoe's social media fame has been played on once again by Mercedes' social media team, in a post on their official X account.
In a rundown of important events in October, including the United States and Mexican grands prix, Mercedes included Roscoe Hamilton's 12th birthday, much to the delight of their fans.
