Her full 'I Knew You Were Trouble.' video is set to premiere Thursday at 4:40 p.m. ET on MTV.

Taylor Swift unveiled a teaser clip for her brand-new "I Knew You Were Trouble." video Wednesday night (December 12) during our "Big & Best of 2012" live stream ... and based on what we've all just seen, this one's shaping up to be unlike anything she's done before.

The teaser opens with Taylor sprawled out in a desert, the signs of a truly epic party scattered around her. In a series of lightning-quick flashbacks, we see her whirling in a field of bright lights, hands held aloft, lost in the moment. Meanwhile, back in the present, she definitely looks worse for wear, her punky pink hair matted to her head, her tank top tattered.

And, from the sound of it, things don't get much better from there. As Swift explained earlier this week, the "I Knew You Were Trouble." video follows her "really toxic relationship" with "Spider-Man: Turn Off the Dark" star Reeve Carney, and it definitely delves depths she's never explored before.

"We knew we wanted it to be [about] some sort of corruption — good girl is living her life, going on about her life ... and all of a sudden she runs into this force. This guy is just like a force," Swift said. "She'll do anything to fit into his world, including change about herself."

The full "I Knew You Were Trouble." video will premiere Thursday, December 13 at 4:40 p.m. ET during "MTV First: Taylor Swift," and will immediately go into rotation across all MTV channels. Fans will also be able to watch the video on demand at TaylorSwift.MTV.tv. And if the final product is half as good as the teaser, well, let's just say you're going to be watching it over and over again.

Don't miss the premiere of "I Knew You Were Trouble." during "MTV First: Taylor Swift," airing tonight on MTV at 4:40 p.m. ET!
