Andy Cohen Shares Heartfelt Message to Mary Cosby After Her Son’s Death: ‘You Did Such a Good Job’

“Our beloved son Robert Jr. has been called home to the Lord,” Mary shared in a statement to Us. “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.”

Robert Jr.’s addiction battle was featured on RHOSLC throughout the past two seasons. Viewers often applauded Mary for her candid approach to opening up about her son’s struggles.

Cohen previously shared his condolences while speaking on the Wednesday, February 25 episode of SiriusXM’s “Andy Cohen Live.”

“We’re so sad to read the news about Mary Cosby’s son, Robert and I can’t think of anything worse than losing a child and in this way,” he said. “[Cohost] John [Hill], you and I have talked so much on this show about addiction and the heartbreak that is associated and I have so much love for Mary.”

Cohen shared that he spoke with Mary for “a while” on Tuesday, February 24 — one day after Robert Jr. died, emphasizing that this is “every parent’s worst nightmare.”

“You and I talked about this too, just about how much respect we had for the way that she spoke to Robert when we saw them talking about this on air and what I really admired was that she kind of met him where he was in a way, and she was kind of gently steering him or guiding him,” Cohen said.

Cohen recalled that Robert Jr. was in jail when the RHOSLC season 6 reunion was filmed. (Robert Jr. violated a protective order in 2025. He pleaded guilty to the charges and was released from jail earlier this month.)

“She was really hoping that he would be scared straight and I guess that didn’t happen,” Cohen claimed. Cohen added that they are “sending all our love to Mary and Robert.”
