Well my list is the following and I can tell you that Demi Moore does have pretty feet but I don't think she is ticklish on them, She had her feet washed in a movie G.I. Jane by her then boyfriend and she did not even crack a smile or giggle at all. But anyway my list is as far as celebrites go are:
1. Nicole Kiddman
2. Goldie Hawn
3. Drew Barrymore
4. Paula Abdul
I know that all 4 of these celebrities are ticklish as I have seen them tickled in movies or on t.v. or they have admitted being ticklish.
