The news of Robert Jr.’s death was met an outpouring of condolences for Mary and her husband, Robert Cosby Sr., including from several of her RHOSLC cast members.
“Sending you all my love Mary. So sorry for your loss,” commented Whitney Rose.
“I’m so saddened and sorry,” wrote Britani Bateman. “Sending love and prayers.”
“Thank you for sharing Bubbs with my family and the world,” Angie Kastenevas shared. “He touched many hearts and this loss has broken mine. I will forever remember his kindness towards Elektra, his handshake and eye contact, and his soft spoken voice “Love you Mom” I am here for you..May god bless your family and may his memory be eternal. I love you Mary.”
Many other members of the Bravo family also shared works of support with Mary, including Kyle Richards, Wendy Osefo, Candiace Dillard Bassett, Gretchen Rossi, and Cynthia Bailey.

Mary Cosby’s son opened up about his struggles on ‘The Real Housewives of Salt Lake City’
Robert Jr. faced addiction and legal issues in the years before his death. He was arrested in 2022 for a DUI. In late November 2025, he pleaded guilty to assault and trespassing charges stemming from an incident with his estranged wife and father-in-law. He was released from jail earlier in February after serving two months.
Mary’s only child appeared occasionally on The Real Housewives of Salt Lake City alongside his mother and father, Robert Cosby Sr. In a season 5 episode, he opened up about his drug use and suicidal ideation, telling his mother she was “the only reason I didn’t kill myself.”
“You have to know I love you more than anything, more than anything in this world,” Mary replied. “I think I love you more than dad — don’t ever tell I said that. But you’re my friend, you’re my son, you’re my gift. God gave you to me. You’re the only thing that ever made me happy. Before I had you I was never happy. You came, and you were so real. You was everything I hoped her in a person.”
