Katy Perry Videos: Katy Perry and Kanye West go sci-fi in a music motion picture: Katy Perry and Kanye West go sci-fi in a music video for their joint track "E.T." The wife of Russell Brand transforms from an extraterrestrial creature to an otherworldly goddess with braided hair and colorful make-up while floating through the space. Meanwhile, the G.O.O.D Music rapper is dressed casually in jeans, T-shirt and leather jacket as he raps his verses inside an orb-like flying object.

Talking about getting her make-up done, Katy told MTV, "It was, like, five and six hours, each makeup look." She undergoes three different looks of her alien character. One sees her in red-blue-and-white make-up with an all-white ensemble, another has her in flaming-red look with a matching get-up, and the other features her wearing a gold breastplate.

"It was hard for me! It was really a patience thing for me on this video," she said of the challenge in going through the extensive makeup process. "But, you know, it's like when you're doing a film. Sometimes you have to do prosthetics, and you have to get really old or turn into an animal or a monster - and that's kind of what this process was.

"E.T." is taken from Katy Perry's 2010 summer effort "Teenage Dream". The song actually is a solo track, but she adds Kanye West's verses to the radio's version. The revamped tune is currently sitting at No. 1 on Billboard Hot 100.
