Megan Mullally, with whom Morrison often shared the screen during her time on Will & Grace, responded to the news by writing, "thank you for your friendship & partnership, Shell." Eric McCormack wrote, "Shelley was a beautiful soul [and] a wonderful actor. Her work as Rosario, season after season, was as nuanced and real as it was hysterical."

Debra Messing said, "Shelley had a career that spanned decades, but she will always be our dear Rosie. She was a kind soul with a huge heart and always had a smile on her face." And Sean Hayes wrote, "She was absolutely hilarious and had the biggest heart."
