London: After her chart-topping collaboration with Snoop Dogg, pop star Katy Perry has joined forces with another rap superstar, Kanye West, for her new single `ET`.

`California Gurls`, her song with Snoop became a hit and Perry has added West`s verses in the radio version of her new single, though she goes solo in the album.

To top it all, Perry has invited the `Stronger` hitmaker to join her in the song`s music video, reported Ace Showbiz online.

A behind-the-scene picture of the video shoot has gone viral. The image shows Perry dressed as a imaginary alien.

In the photograph the 26-year-old singer is wearing white-red-and-blue make-up with a silver headpiece and posing next to Kanye who dresses casually in a black jacket.
