2 Broke Girls actress Kat Dennings revealed how Heff was lovely to her mother.

Hefner's son Cooper Hefner, the chief creative officer of Playboy Enterprises, said in a statement: "My father lived an exceptional and impactful life as a media and cultural pioneer and a leading voice behind some of the most significant social and cultural movements of our time in advocating free speech, civil rights and sexual freedom.

"He will be greatly missed by many, including his wife Crystal, my sister Christie and my brothers David and Marston and all of us at Playboy Enterprises."

"Hef changed my life. He made me the person I am today. I couldn't be more thankful for our friendship and our time together. I will miss him so much but he will be in my heart forever," she said in a statement to People.
