Taylor Swift fake: more interested in the original pic

Here's a pretty good Taylor Swift fake I found. I'm more interested in who the model is doing the tickling so I can try to find out if she's tickled in other videos, assuming they didn't put a celeb's face on her too. If they did I don't recognize her. Even if you just recognize the studio it was taken from it would be helpful. Thanks.

If I had to guess, I think that's one of the girls from Czech Tickling. Her face is familiar but I can't quite put a name to it!
