Katy Perry is giving Lady Gaga a run for her money in the world of epic music videos.

This week, the super-popular artist released the official video for her new single 'E.T.,' a literally out-of-this-world production that features everything from aliens, to elaborate costumes to an appearance by featured artist Kanye West.

In fact, it could be the most epic video she's done to date (unless, of course, you're more into things like fireworks or candy and Snoop Dogg).

The video release comes at a perfect time for Perry; today, 'E.T.' reached number one on the Billboard Hot 100 singles chart, marking her fourth number-one single off her Grammy-nominated CD 'Teenage Dream.'

Watch the video below, then tell us: Is this Perry's best music video to date? Or is she phone-home-ing it in?
