Kathy and Garcelle made a rare appearance together for charity on Tuesday, staying joint at the hips all night for The Abbey's 16th annual Christmas In September event.

The restaurant was the hottest place to be in West Hollywood, CA, with celebrities like Paris and Nicky Hilton, 'RHOBH' alum Kim Richards, and more walking the red carpet and collecting toys for the Children's Hospital of Los Angeles.

The paparazzi snapped away while Kathy posed with her daughters — but they really went wild when Garcelle and Kim joined in.

Kathy kept it fashionable in a red and white dress while clutching a festive purse that read, "Mrs. Claus." Garcelle slayed in a curve-hugging two-toned number and Kim followed suit with her big sister in a checkered dress with a belt.
