The 'Firework' singer's mum says she won't watch her daughter on MTV as the star discusses her "rebel" phase.

Katy Perry has unveiled a new teaser clip form her upcoming debut 3D concert movie Katy Perry: Part Of Me which shows the star discussing performing on MTV for the first time with her heavily religious parents.

The 'I Kissed A Girl' star can be seen asking her mum if she would watch her on the music TV show, to which her mother responds "no" adding: "I'm not going to watch you if you've got half your clothes off".

The footage features an 18-year-old Katy talking to camera about how she feels she may be enduring somewhat of a "rebel" phase in her life.

"I thought that I was never allowed to think for myself and all of a sudden my heart wants to do all kinds of things," she confesses, adding: "I guess I'm just going through a rebel phase I don't know."

The star's movie will hit cinemas on 5^th July, and the singer recently admitted that it will feature "everything" – including details on her marriage breakdown to Russell Brand.

Meanwhile, Katy will be taking to the stage at Wembley Stadium on Saturday (9^th June) for Capital FM's Summertime Ball 2012 performing with the likes of Jessie J, Kelly Clarkson and opening act Coldplay.
