Katy Perry's 'E.T.' Video Premieres -- Watch It Now!

New clip with Kanye West is a big-budget spectacle that takes Perry to the next level.

We've seen Katy Perry camp it up in "California Gurls" and go glam in "Thinking of You" and "Teenage Dream," but we've never seen her get extraterrestrial — until now, of course.

Because in her new video for "E.T." — which premiered Thursday (March 31) on MTV.com — Perry plays the titular alien: a swirling, shifting, otherworldly being who crashes to earth to resurrect a long-dormant love and, in the process, perhaps reboot the human race (since, as is often the case with sci-fi exploits, planet Earth has undergone some sort of cataclysmic apocalypse and is now bereft of life). At least, I think that's the plot of the thing, though, really, it's not all that important if I'm wrong. Find out the full story tonight on "MTV First: Katy Perry's 'E.T.'," which bows on air at 7:53 p.m. ET before tossing to an MTV.com live stream, featuring MTV News correspondent Sway's exclusive chat with Perry, an interview with director Floria Sigismondi and reaction from Perry's fans.

"E.T." is a huge-looking, quick-moving blockbuster of a clip, overflowing with eye-catching special effects, opulent costumes and artfully applied makeup (and Kanye cameos), the kind of production where a plot is basically an afterthought. In other words, it's a Hollywood-level spectacle, a summer smash that just so happened to come out in the early days of spring. It's an event.

And really, with each #1 single she notches, it's the kind of clip Katy Perry has earned, one that puts her on par with other pop megastars like Britney and Gaga in the sheer scope of the production.

Working with acclaimed director Floria Sigismondi, Perry has created a video that certainly ranks among her very best and is unquestionably the biggest thing she's ever done, a production preceded by glossy teaser clips and online "abductions." The mind boggles at the cost of the wardrobe and hair extensions alone.

But, much like the plot, none of that really matters. "E.T." is less about the insignificant details and more about the larger picture — a video that not only moves Perry to the upper echelon, but looks and sounds great. It's a widescreen, THX-ian type of thing, meant to be marveled at. Whether or not you do, you can't deny that KP has earned the right to make it. She's finally arrived: fallen from the heavens to take her rightful place among the elite. Welcome our new alien overlord.
