E!Joan Rivers was a force of nature to work with, and she has forever touched the lives of those lucky enough to call her a friend and colleague.
"It is almost impossible to describe how much I adored Joan and how much she has meant to me," E! News host Giuliana Rancic, who also co-hosted Fashion Police with Joan, said in a statement following the comedic icon's passing today at the age of 81.
"She was not only the funniest woman I have ever met but was incredibly loving, honest, and lived her life with no regrets. Working with her for the last 13 years has been one of the true joys of my life. She could put a smile on your face, instantly, no matter how hard your day was."
"My heart goes out to Melissa and Cooper who have lost something that can never be replaced," Giuliana continued. "Their bond was truly one-of-a-kind. They had the greatest mother and grandmother anyone could ever hope for.
"My life is so much fuller and happier because I got to share it with this beautiful person, a true genius. I woke up today unable to grasp what the world will be like without her and at the same time feel so privileged to have called her my friend."
It truly is hard to believe that just last week, on Aug. 26, Joan was happily reviewing Emmys and MTV VMAs fashion with Giuliana, George Kotsiopoulos and Kelly Osbourne on Fashion Police.
"Rest in peace @Joan_Rivers. Thank you for changing my life. I will miss you so much," George tweeted today in response to the sad news.
"I'm completely heartbroken by the loss of my beloved Joan," Kelly wrote on Facebook about the dear friend she often called "Grandma Joan."
"Not only was she my boss, she was and will always be my teacher, therapist, closest friend, inspiration and the only grandmother I ever knew. She was family and I will never forget her. Laughter will be difficult for a while but when I'm sad, lonely or upset all I will have to do is think of Joan and a smile will cross my face. Laughter is what she gave us and laughter is what she would want us to do in remembrance of her.
"Melissa and Cooper, my thoughts are with you and I love you both so much. Joan, thank you for taking me in and loving me as a daughter. I will miss you deeply and will always hear your voice in my head saying ‘my darling get out there and be you!'"
"E! and NBCUniversal send our deepest condolences to Melissa, Cooper and her entire extended family on this incredibly sad day," the network remembered Joan on Thursday. "For decades Joan has made people laugh, shattered glass ceilings and revolutionized comedy. She was unapologetic and fiercely dedicated to entertaining all of us and has left an indelible mark on the people that worked with her and on her legions of fans. She's been a much beloved member of the E! family for over 20 years and the world is less funny without her in it. Today our hearts are heavy knowing Joan will not be bounding through the doors."
