Kanye West Joins Katy Perry On 'E.T.'

Fourth Teenage Dream single to be released this week.

In her next single from Teenage Dream, "E.T.," Katy Perry sings about falling in love with an alien to a spacey dance track. And unlike in the version on the album, the radio version features the extraterrestrial stylings of Kanye West.

The rapper not only makes a cameo on the song, but he will also appear in the video alongside the California Gurl. The video was shot by "The Runaways" director Floria Sigismondi, who is known for putting her dark, feminine spin on clips for artists like Christina Aguilera, Marilyn Manson and the White Stripes.

Little else is known about West's contribution to the song and the video, but in a photo released by Perry's label, Kanye appears in regular street clothes while Perry looks like perhaps she's playing the alien character she sings about in the song — complete with pastel-colored makeup and giant braided headpiece. In fact, the look harks back to some of the costumes former Sigismondi collaborator Björk has worn in the past.

Last month, Perry released artwork for "E.T." In the black-and-white photograph, Perry sports blunt bangs, heavy cat-eye makeup and an elaborate top.

Perry has made it known that she wants the videos for her Teenage Dream songs to be over-the-top. "I'm looking forward to making music videos on this new album," she explained. "There's a story to the songs. ... I'm really excited about ... making those music videos that are going to be larger than life."
