I'll explain mine, if you'll explain yours.
Since I don't know either one of these women, and have never had a conversation with either one, I can only judge them by Public appearances and reputation. I see how each of them conducts herself. Jodie Foster, is a known Lesbian who is confident enough of her magnificent acting ability to be happy with herself and what she has created, with no Public display of her private life, nor any criticism of it. Her ability as an actress. Her beauty and good taste are undeniable. She is an elegant, independent Woman.
Kelly Preston, on the other hand, is a Scientologist, married to another Scientologist. They lost a Son, and while a tragic event, possibly could have been prevented had proper care been given him by his Mother, Kelly Preston. Rumor has followed Kelly and her Spouse for years. I have seen her at events looking as tho she is stoned, and has slept in her clothes. She is not an accomplished Actress, altho she has worked in the business when opportunity presented.
Your turn, although it seems a bit preposterous to be discussing 2 people that (probably) neither of us has ever known.
