She appeared on the cover of the July 15, 1986 issue of Soap Opera Digest with her close friend and Guiding Light co-star Christopher Bernau. It is the only time she has been on the magazine's cover.
She is an animal lover who supports a variety of animal charities. She once found a cat in the parking lot of a theater in L.A. which she adopted and named Bob.
When Mary Kay auditioned for the role of "India" in 1984, Guiding Light producers had a very different character in mind. Originally the part was written as a shy country girl and cousin to the popular "Beth Raines." After Mary Kay won the part, it was changed into a European Baroness, to fit her own personality.
Mary Kay Adams: (comparing herself and her "Guiding Light" character India) India is capable of the real emotion, real loyalty and real love. But living on the edge and society fluff... that doesn't appeal to me. The clothes that India wears are not from T.J. Maxx! India is not content until she's wearing the very expensive designer couture. I'm excited when I get corduroy pants at the Gap for 20 bucks!
Mary Kay Adams: I think working on Star Trek: Deep Space Nine is the most fun I had in Hollywood. I say this very honestly. The first time I walked onto the set of DS9, I kept saying 'Pinch me. Pinch me, I'm on Star Trek'. I was very excited, very happy. I really like the entire environment on the show.
