When I first heard about "Part of Me 3D" I thought it was just going to be the "California Dreams Tour" in film format so when I saw the teaser trailer, that it's actually gonna have everything from the beginning of Katy's career, I was surprised and immediately got very excited about it.
To be totally honest, watching the full trailer had me tearing up and having goosebumps all over. I loved Katy from the start of her mainstream pop career so I can say I've been a fan for 4 years or so already. With every song and music video she releases, my admiration for her just grows stronger. And after watching the movie, I'm sure my feelings would be magnified even more. :)
