He wrote: "My heart goes out to George's family and I sympathize with the black community and millions of other people around the world who are outraged by these events. It is touching to see that in 2020 this is still happening."
Meanwhile, six-time F1 world champion Lewis Hamilton fought with his fellow drivers for not talking about Floyd's death.
"I see those of you who remain silent, some of you are the biggest stars and still remain silent in the midst of injustice," wrote Hamilton on Instagram.
"It is not a sign of anyone in my industry that, of course, it is a sport dominated by whites. I am one of the only people of color there, but I am alone.
"I would have already thought that you would see why this happens and say something about it, but you cannot stand by us. Just know that I know who you are and I see you.
