Dean Geyer was a little shy during the filming of the "Oops!... I Did It Again" number, and Lea had to tell him "Why aren't your hands on me? It's OK. You can actually touch me!". A few moments later, when asked by Dean how far down he could drop her as she split open her legs, she told him: "Don't you worry. I can go all the way down to the floor." And she did.
There are at least three So You Think You Can Dance (2005) all-stars dancing in the "Oops!... I Did It Again" number.
