Taylor Swift is #1 on my list in terms of celebrities whom I want to find out whether or not they're ticklish. She goes barefoot A LOT, or she used to, in her music videos and at concerts. She shows off her feet a lot as well. But she's very aware of how people view her online and fetishist, and I think she's careful to reveal or allow certain things, like tickling, whether it's conscious or sub-conscious. She's become very high profile and still no confirmation or anything. Many other big name celebs at this point have revealed or been tickled one way or another.
In terms of who I want to tickle? Who knows. My interests change day to day. Right now, probably Lex Scott Davis, from a recent movie I watched on Amazon - Ricky Stanicki (decent movie).
