Katy Perry will give a special live performance at the premiere of her 3D movie Part Of Me this evening.
The 'California Gurls' singer will take to the stage on the famous Hollywood Boulevard outside the Grauman's Chinese Theatre tonight (26th June) to offer fans a special treat as she officially launches the film.
The star yesterday attended a press junket for the movie in Los Angeles wearing a pink flowery short dress as she posed for photographers.
The film follows the singer during her 'California Dreams' world tour and through the struggles she undertakes during the marriage breakdown to comedian Russell Brand.
Katy recently confessed that she still believes in marriage despite her divorce and "regrets nothing" during the time she spent married.

The 'Firework' singer recently premiered the official music video for her new song 'Wide Awake' - which was written for the movie - and confessed that it is the "perfect" closing chapter on her 'Teenage Dream' album and era.
