Even if that is true in the US, and I don't even like Selena, I don't think that is correct for the rest of the world. I personally don't know anyone that knows who Chris Rock is in my country.
This is just out of curiosity
I already answered, why does it matter if he is or not? He still wins since he makes more money than Selena. I rather be more successful than be known.
Nobody is mad you're all being delusional
One thing is to like the joke and LOL , another thing is to say he is bigger than her when most people literally don't know him
