Cast members from Real Housewives of Salt Lake City have publicly shown their support to colleague Mary Cosby following the death of her son, Robert Cosby Jr. He was 23-years-old.
Mary, who has been part of the show on-and-off since its debut in 2020, confirmed the tragic news on her Instagram page after his passing was initially reported by TMZ.
“Our beloved son Robert Jr. has been called home to the Lord,” she wrote. “Though our hearts ache, we take comfort in God’s promise and in knowing he is finally at peace. We are grateful for your prayers and trust in the Lord to carry us through this time of sorrow.”
Mary’s castmate and close friend Angie Katsanevas responded to her post, saying: “Thank you for sharing Bubbs with my family and the world. He touched many hearts and this loss has broken mine.
“I will forever remember his kindness towards Elektra [Katsanevas’ daughter], 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.”
