Katy Perry’s new 3D movie hits theatres July 5th so to celebrate, Katy shut down Hollywood Blvd! The entire street was shut down and there was a huge stage and an elevated PINK carpet for the stars to walk on! Katy performed for tons of fans who were waiting all day to see her sing her hits!

Popstar! got to chat with Katy, Rebecca Black, and Carly Rae Jepsen on the red carpet!
