Pop star, Katy Perry, just dropped the official music video for her fourth single, “E.T.,” off her Teenage Dream album, in which she enlists hip-hop superstar Kanye West.

The Floria Sigismondi-directed clip has a sci-fi vibe, in which Perry stars as an alien princess who finds love on Earth; while West comes in floating in space as he spits lyrics about extraterrestrial relations.

Check out the video to take a galactic journey.
