Ron Howard is devastated by the death of “American Graffiti” co-star and close friend Cindy Williams.

Cindy Williams died last week (on Wednesday, January 25) after a brief illness, according to a statement from her family.

She was 75 years old when she died. She was best known for her role as Shirley Feeney on the sitcom Laverne & Shirley.

“The loss of our kind, hilarious mother, Cindy Williams, has brought us insurmountable sadness that can never truly be expressed,” her children said.

“Knowing and loving her has been both a joy and a privilege for us. She was one of a kind, beautiful, and generous, with a brilliant sense of humor and a sparkling spirit that everyone adored.”
