Publishing legend and founder of Playboy magazine Hugh Hefner died Wednesday of natural causes at age 91. Some of the biggest names in Hollywood graced the pages of Hefner’s magazine, among them Cindy Crawford, Lindsay Lohan and Kim Kardashian — among many others.

Upon learning of Hefner’s death, Kardashian took to social media to memorialize the famed publisher. Kardashian shared that she and fellow socialite-turned-reality star Paris Hilton, 36, had reminisced about memories at the iconic Playboy mansion.

“RIP to the legendary Hugh Hefner!” Kardashian tweeted. “I’m so honored to have been a part of the Playboy team! You will be greatly missed! Love you Hef!”

The 36-year-old beauty mogul added: “Paris & I are reminiscing about the Playboy parties at the mansion & how much we love Hef. She’s texts me the perfect Hef emojis,” and included both the Older Man and Woman With Bunny Ears emoji.

Kardashian also retweeted a fan who shared photos from her Playboy cover in 2007 that was one of her first for a major magazine.

The magazine in 2015 shared an image of the star from her 2007 cover shoot wearing her iconic red ensemble.

While the star had an infamous meltdown over her 2010 nude cover shoot for W magazine — as witnessed on a 2011 episode of the E! spin-off series “Kourtney & Kim Take New York” — Kardashian has since appeared bare for several outlets. The star has posted a number of nude selfies on her Instagram account and has posed nude for magazines that include Paper, GQ and others.

Facing backlash for one 2016 selfie in particular in which she was snapped posing nude in her bathroom, the star later took to her blog to address the backlash.

“I am empowered by my body. I am empowered by my sexuality. I am empowered by feeling comfortable in my skin. I am empowered by showing the world my flaws and not being afraid of what anyone is going to say about me,” she said. “And I hope that through this platform I have been given, I can encourage the same empowerment for girls and women all over the world.”
