Katy Perry launched her 3D concert movie in Hollywood last night (27th June) with a spectacular event complete with a surprise live performance from the 'Teenage Dream' singer.

The 'Firework' star stepped out at the premiere of Part Of Me 3D yesterday at the Grauman Chinese Theatre on Hollywood Boulevard in Los Angeles, dressed in a short red dress and heels, while walking a specially designed pink carpet for the film's launch.

Katy was seen arriving at the star-studded event alongside her 90 year-old grandmother Mary Perry Hudson, who features in several scenes throughout the film.

The premiere was also attended by some of the world's biggest stars right now including Justin Bieber, Selena Gomez and Carly Rae Jepsen.

The 'California Gurls' singer has promised fans the film will reveal intimate details about her personal life, including her separation from husband Russell Brand during the end of her 'California Dreams' world tour at the end of 2011.
