Where can I get the version of the movie that has the girls making a Musica video in the gym instead of just working out?

I have bought the movie 3 times and while all my bought versions have been the same, there has been one major thing different from the version I first saw that made me fall in Amore with the movie. In all the versions I bought, the girls are simply working out in the gym scene. In the version I first saw, the girls were in the gym to shoot a video. I know I'm not imagining it because of te watch the trailer, there's a guy lifting weights that's not in the gym scene in the versions I bought. A few other differences that made the movie even più amazing to me, but that's the main thing that stands out in my mind. Anyway, any other fan out there know what I'm talking about and where I can get a copy of it?
