On Wednesday, Playboy founder Hugh Hefner died at 91 years old. And while the publishing giant and his business were often controversial, he was also revered and beloved by many, and tributes from people who worked with or knew him have poured in since his death.

Pamela Anderson, who appeared on the cover of Playboy a record 14 times, posted a particularly moving tribute to “Hef,” as he was known.

“You taught me everything important about freedom and respect. Outside of my family, you were the most important person in my life,” Anderson wrote alongside a video in which she’s seen weeping.

“Everything anyone loves about me is because you understood me. Accepted me and encouraged me to be myself,” she wrote. “You said, I can hear you say — be brave. There are no rules. Live your life.”

Kim Kardashian, meanwhile, tweeted that she was “so honored to have been a part of the Playboy team,” and reminisced with her old bestie Paris Hilton about some of the times they shared at the famous Playboy Mansion. “She texts me the perfect Hef emojis,” Kardashian wrote, using a string of the bunny-eared dancing girl emojis alongside the old man emoji.

Jenny McCarthy wrote that he was a revolutionary not only to culture at large, but also to her life. “Thank you for being a revolutionary and changing so many people’s lives, especially mine,” she wrote alongside a ’94 Playboy cover of hers. “I hope I made you proud.”

Hef’s Girls Next Doors costars Kendra Wilkinson and Bridget Marquardt also paid tribute, with Wilkinson telling People in a statement, “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.”
