Rossi's post garnered thoughtful messages from throughout the \"Real Housewives\" universe, including \"RHOC\" stars like Vicki Gunvalson, Heather Dubrow and Lydia McLaughlin to name a few. \"Real Housewives\" executive producer and reunion host Andy Cohen also sent condolences.

Smiley-Arroyo's mother Michelle Arroyo also shared a sweet post dedicated to her son in which she revealed he died Sunday night.

\"I’m still in shock and going through the motions of dealing with all the details,\" she wrote.

\"I know Gray is playing cards with Gramma and playing Trouble with our beloved Diane,\" she added. \"His dog Mo is right at his side as he never left him.\"
