Katy Perry walks the red carpet and performs for the world premiere of “Katy Perry: Part of Me 3D.”

The film premiered at the Grauman’s Chinese Theater in Hollywood, CA. June 26. Not only did Perry show up in old Hollywood-esque red velvet Dolce&Gabbana, but also gave a special live performance for the first-ever Pepsi/Billboard Summer Beats series.

You can check out some pictures and footage from the event below the post.

“Katy Perry: Part of Me 3D” follows Perry’s on- and off-stage life, including behind-the-scenes footage, home movies and concert footage of her California Dreams Tour.

Perry’s goal for the film is for her fans to get an inside look into her life. “For the last year and a half, I have intimately documented my life both on and off the stage of The California Dreams Tour,” she said. “I want to take you behind the cotton candy clouds and reveal the highs and lows and nuts of bolts of this extraordinary ride. I promise you, after seeing this film, you will truly know me.”

“Katy Perry: Part of Me 3D,” released by Paramount’s Insurge Pictures, will be in theaters July 5. You can see a sneak peek of the film July 2 (learn more about that here). You can learn more about the film through its official site, Facebook, YouTube, Pinterest and Twitter.
