One of her music videos has what looks to be a very very brief foot tickle scene. Cant remember the name of the song, it wasnt poker face or paparrazi though.
Just watched the video. It looks like the guy is trying to give her a foot rub and she pulls away because it tickles. Even though she has shoes on for almost all the video the camera does focus on her feet quite a few times. She's a cutie!
This still belongs in the ticklish celebrities section. Good spot Persian for the breif tickle in the vid. He or she or whatever, ticklish is ticklish.
