Katy Perry has a documentary about herself.
Anyway, for its premiere, she took to the red carpet in a strapless Dolce & Gabbana dress. The velvet frock with a sweetheart neckline was also worn by Sonam Kapoor back in May.
I have to say, much preferred the way Sonam wore this dress; I can't believe Katy paired it with matching pumps.
