McGowan and Argento became close after both came forward with allegations that the movie mogul raped them, with Argento also appearing on the actress' E! series, "Citizen Rose." Bourdain was a vocal supporter of them both and, in November, cooked dinner for them and accuser Annabella Sciorra.
"Anthony I am so mad at you. You were so loved, the world is not better without you," Rose posted on Twitter Friday morning. "I have a message for those considering suicide as a solution to a temporary problem. Please call a hotline. Please reach out. Asia needed you, Anthony. We needed you. Please come back."
In the accompanying video, McGowan cries as she says, "For those considering suicide, please don't. Please call for help, because it's a permanent solution to a temporary problem. It's not forever and the world will not be better off without you. Oh Asia Argento, you've been through so much, Anthony why? Please call suicide hotline, this will affect people all over the world because Bourdain was international."

She also shared one of Asia's recent photos of Bourdain on her own Instagram page, captioning the shot: "Asia loves you. Your daughter loves you. Anna and Nicola love you. You were not just loved, your were beloved. And you chose a permanent solution to a temporary problem. She needed you. We all needed you. Please if you are at the edge, reach out to a hotline or a doctor. Do not choose a permanent solution to a temporary problem. Oh, Bourdain. Please come back. Asia. My Asia. Who has been through more than most could bear. I wrap my arms around you."
