Never Say Never? So 2011.
The concert documentary that's sure to rock pop music fans' worlds this summer is Katy Perry's Part of Me, which hits theaters July 5.
The 3D flick gives fans a glimpse into the "Firework" singer's colorful, cartoon-like world--and tells the story of how Perry, 27, became the international superstar she is today.
"Songwriting and making these records are the truth of who I am," Perry--who split from husband Russell Brand in January--admits in the clip. "[My songs] are like a mad diary."
Later, the emotional pop star can't contain her joy during a stop on her tour. "Thank you for believing in my weirdness!" she yells to her crowd.
