Retired from Saks Fifth Avenue in 1994 to care for her close friend Claudette Colbert, who had suffered a stroke the previous year. When Colbert died in 1996, she had left the bulk of her estate to O'Hagan.
[on her close friendship with Claudette Colbert] I was working at Saks and had to be in bed much earlier than Claudette. But if she saw that I had fallen asleep, she'd wake me up in order to talk. She needed somebody with her all the time. There was a 27-year age difference between us. So I was like her daughter. We were very lucky to find each other at that time in our lives.
