Pop sensation Katy Perry has unveiled a brand new teaser trailer for her upcoming 3D concert film, 'Part Of Me'.

The movie will be released around the UK and USA in cinemas from July 5, and the 'Teenage Dream' hitmaker has now shared yet another clip from it with her followers around the world.

In this new preview, Perry can be seen talking about her suggestive hit 'I Kissed A Girl' and how her parents reacted to it: "I think people love the idea of a good girl gone bad, and they think my parents have disowned me, but that's not the story at all."

Her sister, Angela Hudson, also opens up about how Katy initially asked her to relay the news to their religious mother and father: "When Katy decided that 'I Kissed A Girl' was going to be her first single, I said, 'Have you told mum and dad?' and she said, 'No, can you?'"

Earlier today (June 13), she treated her fans to a sneak peek of her forthcoming music video for 'Wide Awake'.
