Since making the switch from McLaren in 2013, the 39-year-old has won six world titles, but has been surpassed as the sport's dominant force in recent seasons by Red Bull star Max Verstappen.
It's almost three years since the Brit last tasted victory, and he has looked a long way off the pace in 2024 during what has been a disappointing final season with the team.
His future partner Leclerc has now admitted the pair have spoken about teaming up in 2025, and have already taken steps to forge a positive relationship which he hopes will help get Ferrari back to the top of F1.
Speaking to the media, the Monegasque confirmed their recent discussions have covered a wide range of topics.
On the topic of said conversations, Leclerc said: "I think it is mixed - maybe a little bit about the way it is now, with Ferrari and where we are at.
"But this is a very little part of our discussions. He is still 100 per cent focused on his season, this season, with Mercedes.
"So we cannot exchange about everything yet, of course, but just in preparation of next year, maybe of our common passions - design, fashion in general.
"But then 80 or 90 per cent of what we speak about is just private stuff, how life is going, music."
With Mercedes looking stronger off the back of the Austrian Grand Prix, 2025 will bring a new challenge for both Hamilton and Leclerc as they each navigate their new relationship at Ferrari.
