Robert Sr. made an appearance on part three of the RHOSLC reunion on Wednesday alongside his wife, where he addressed Jen Shah's controversial "grandfather f---er" comment. "This granddaddy junk is stupid," he said. "I was 22 years old when I married [Mary's grandmother], now whose granddaddy was I? I wasn't even anybody's daddy yet. I don't like that. I don't like that at all." Mary wed Robert Sr., her late grandmother's second husband, in an "arranged" marriage. The two have been together for over 20 years and share a teenage son, Robert Jr. Bravo RHSLC's Mary Cosby Says Her Marriage to Step-Grandfather Was 'Arranged' — 'We Are Blessed' Earlier in the season, Jen insulted Mary's marriage within earshot of her costar during an especially heated moment at a party.

"I love her." Jen apologized to both Robert Sr. and Mary, admitting that she was out of line. "You don't have to worry about," Robert Sr. replied.
