First Britney Spears went allMatrixin her video for "Hold It Against Me." Then Lady Gaga gave birth to a new generation of Little Monsters in her "Born This Way" video. Now, Katy Perry has ventureed into the realm of sci-fi with her cinematic video, "E.T."
Kanye West guests on the spacey dance track, which Perry says is about "falling in love with a foreigner, like far away ... Not even in England." And the video brings that theme to life, as alien goddess Perry floats down from space in a search-and-rescue mission for her lost love.
