As noted in the slideshow below, a host of celebrities have gathered on social media to say goodbye to Hugh Hefner.

The Playboy founder, who died this week at the age of 91, came into contact at various points with nearly everyone in Hollywood, while helping to shape the careers of such stars as Kim Kardashian, Kendra Wilkinson and Pamela Anderson.

And perhaps no one is taking his death harder than the former Baywatch beauty.

Pamela Anderson Cries

Anderson was so closely associated with Playboy that she graced the cover of its final nude issue in late 2015, prior to the magazine ridding its page of all naked models.

(This was a decision it then reversed, thankfully, just over a year later.)

To honor the man who made her a household name and for whose publication she stripped down on numerous occasions, Anderson shared a poem with her Instagram followers.

She also posted a video in which she fights back tears for nearly a full minute before finally steadying herself long enough to simply say “Goodbye, Hef.”

Check out that emotional video here:

In her poem, titled Goodbye #Hef,” the actress looked back at her friendship with the iconic publisher as follow:

Mr Hefner / I have so many thoughts, I have no brain n right now to edit / I am me because of you / You taught me everything important about freedom and respect.

Outside of my family / You were the most important person in my life. / You gave me my life… People tell me all the time / That I was your favorite… / I’m in such deep shock. / But you were old, / your back hurt you so much.

Last time I saw you / You were using a walker. / You didn’t want me to see. / you couldn’t hear. / You had a piece of paper in your pocket you showed me – / with my name Pamela with a heart / around it.

Now, / I’m falling apart. / This feeling is so crazy. / It’s raining in Paris now. / I’m by the window. / Everything anyone loves about me is because you understood me. / Accepted me / and encouraged me to be myself.

Love like no one else. / Live recklessly / With unfiltered abandon. / You said the magazine was about a girl like me. That I embody the spirit you fantasized about. ‘ I was the one. /You said.

Over the years, Anderson covered Playboy a record 14 times.

She signed her poem “Your Pamela” and concluded it like this:

I can hear you say – / Be brave. / There are no rules. / Live your life / I’m proud of you. / There are no mistakes.

And with men – / Enjoy … (Your wonderful laugh) / You have the world by the tail / You are a good girl / And / you are so loved – / You are not crazy. / You are wild and free

Stay strong, / Stay vulnerable. … ‘It’s movie time’ / You loved my boys … You were always, always there for us. / With your love / Your crazy wisdom.

I will miss your everything. / Thank you for making the world a better place. / A freeer and sexier place/

You were a gentleman / charming, elegant, chivalrous / And so much fun. / Goodbye Hef.

Emotional stuff.

May Hugh Hefner rest in peace.

NOTE: You likely knew Anderson posed for Playboy, but did you know the stars above did as well?!?
