Katy Perry appears at the premiere of her film 'Part of Me 3D' at Grauman's Chinese Theatre in Hollywood, California on June 26, 2012.
The starlet dazzled in a red Dolce and Gabbana strapless dress. The signature gown was paired with matching pumps and a bedazzled crystal cake slice clutch. Perry, known for her fun and outrageous looks, donned purple hair, dark eyes and rich red lip color.
'Part of Me 3D,' premieres in theaters July 5, and the documentary chronicles Perry's life on and off stage.
