Katy Perry: E.T. video

Here's your chance to watch Katy Perry's new video and see some of the amazing make-up.

The singer has been teasing us with promos for the past week, but all we knew was that it had an alien invasion theme and a confirmed premiere date of March 31st.

It's now here, and we've got the video for you! The single, which features new vocals from rapper Kanye West is the fourth track taken from Perry's 'Teenage Dream' album.

Check out the video below...

Katy has also posted a video giving fans an intimate look backstage of her California Dreams tour!

You'll get to see a make-up free Katy, a Perry in a peacock outfit and a look at the dedication and hard work going into making this her biggest and best tour yet.
