"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!"
Giuliana released a statement to
E! News, saying: "It is almost impossible to describe how much I adored Joan and how much she has meant to me,' she said.
"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".
Other famous faces including Anna Kendrick, Whoopi Goldberg and Ellen DeGeneres tweeted tributes to Joan.
