Based on everything we've seen so far (namely, one teaser trailer), Katy Perry's "Wide Awake" video takes the fairy tale concept to new heights, putting Perry inside a fantastical world and very literally closing the book on her Teenage Dream run.

And while we won't get to see the full video until Monday — when it premieres at 7:53 p.m. ET on MTV as part of "MTV First: Katy Perry" — we've got another exclusive sneak peek for you today, one that shows the dark side of the usually sunny California Gurl.

In this new still from the video, a black-clad Katy (with noir-ish hair to match) clutches a lantern as she makes her way through what appears to be a labyrinth ... though we're still not sure where she's going or who she's searching for. But it bears mention that she looks fantastic — and kinda spooky — while doing it.

We won't know the full story until Monday, when Perry reveals the final chapter in the Teenage Dream story. It's certainly been a fairy tale up to this point, but will she get her happy ending? Tune in to find out.

The "Wide Awake" video makes its worldwide debut on MTV Monday, June 18, at 7:53 p.m. ET as part of "MTV First: Katy Perry," with an exclusive 30-minute interview with Katy and MTV's Sway Calloway to follow on MTV.com.

Her new video will also debut on VH1, Logo and TeenNick, in addition to MTV.com, VH1.com and LOGOtv.com. Katy's fans around the globe will also be able to stream it online at KatyPerry.MTV.com.
