Joyce Lapinsky posted a message on X, showing her gratitude to everyone who sent in "loving tributes" after Richard passed away this week at his L.A. home. On Friday, she said Richard would have been "beyond thrilled and so touched, as am I."

Joyce asked Richard's fans who want to make donations in his memory to send their money to the charity, Comedy Gives Back, or another non-profit of their choice.

As we reported ... The "Curb Your Enthusiasm" star died Tuesday night after suffering a heart attack. Music icon Bette Midler was one of the first people to go on social media to celebrate Richard's life and career. This was followed by a stream of other celebs, such as Ben Stiller, Albert Brooks and his 'Curb' costar Larry David.

Last year, Richard announced he was suffering from Parkinson's disease after he retired from doing stand-up comedy. He said his litany of other health issues culminated in his Parkinson's diagnosis and he was managing it all with medication.
