Justin Bieber did it — now it’s Katy Perry’s turn!
“My concert documentary is coming out Fourth of July weekend. Go and see it and be a firework!” the 27-year-old singer told E! News.
Part of Me 3D also gives fans a glimpse into Perry’s rise to fame and her life behind the music.
“The atmosphere I grew up in was 100 percent Christian. I started singing in church. I never really had another plan,” she says in the trailer.
