I really appreciate you doing that.

“What Sarah Silverman did was so disgusting and so cruel and mean,” said Hilton.

I was trying to hold back my tears so hard.

It was so painful.”

Two days later, Silverman has responded, owning her actions and acknowledging the pain she caused Hilton.

“I felt awful,” she said.

“I never heard back.

I don’t know how that happened.

I’m just real sorry my note didn’t get to her because I really meant it.”

Representatives for Hilton didn’t immediately return EW’s request for comment on receipt of the letter.

I was then and I am much more completely, and with more understanding, I think, now.

I can’t imagine what you were going through at that time."

“Comedy is not evergreen,” she said.

“We can’t change the past so what’s crucial is that we change with the times.

I can imagine Paris is probably reflecting and apologizing for stuff and I say good on her for that.

We both played mean characters and they had our real names.

So Paris, I hope that you accept my apology and I hope that you feel my remorse.

I felt it the second I saw your face that night.
