Kyle Richards revealed that costar Dorit Kemsley is "not so great" after she was victimized by a home invasion.

"The Real Housewives of Beverly Hills" star opened up about how "unbelievably strong" Kemsley was after the robbery during an appearance Tuesday on "Watch What Happens Live With Andy Cohen."

"When it first happened, [Dorit] was unbelievably strong, and I was so impressed by how she handled the situation when it actually happened," Richards told Cohen.

"And then the days after, I think the shock wore off and it hit her, and I think it's going to take her a long time to get over that," she continued.

Richards thinks Kemsley might suffer from PTSD.

"I don't know if you ever get over something like that, you know, having two men in your bedroom in the middle of the night and one man downstairs, and just to be home alone with just your kids is just absolutely terrifying. PTSD, for sure," Richards said.

"My family now needs to start the healing process. I have thrown myself straight back into work as I want our family to return to normality as soon as possible," she said.
