On Jennie Finch's official Instagram she admits to being ticklish!! Idk about you all but she is a long time favorite of mine and I always wondered! You're welcome!
I'm looking at her instagram and the pic u posted with the comments and her answer she supposedly posted. I don't see it when I go to her page and look at that pic
Those were taken when she interned with John Jay and Rich, John Jay said her feet were ticklish and he tickled them, much like Sheryl Crow and Amanda Beard. As far as I know, only pictures of Beard are still online,or were ever online.
