Sexy pop sensation Katy Perry has released a new trailer for her upcoming 3D concert movie, in which her mother can be heard exclaiming she won't watch her on MTV.

In this new promotional clip for 'Part Of Me', the 'Teenage Dream' hitmaker can be heard asking her mother if she's excited to see her on the television, but the response she gets isn't the one she was expecting.

"I'm not going to watch you if you've got half your clothes off," declares Mary Hudson.

Perry also talks candidly about how her views and desires changed as her career began to progress and admitted she felt as though she was "going through a rebel phase":

"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. I wanna travel and experience other things outside of my comfort zone. I guess I'm just probably going through a rebel phase I don't know."
