Watch a preview of Taylor Swift's MTV First interview before it airs on Dec. 13!

Show of hands: Who here can't wait to see Taylor Swift's new video for "I Knew You Were Trouble."? US TOO. You know why? Because along with owning 2012 with the release of her fourth studio album, Red, and unveiling two other flawless, visually-stunning videos for "We Are Never Ever Getting Back Together" and "Begin Again," we're thinking that the laws of pop-star probability would almost guarantee an equally special clip for the third single on Taylor's disc. (The behind-the-scenes photos weren't bad either.) Just a day away from releasing her "Trouble" clip, Taylor will be chatting with MTV News' Sway Calloway tomorrow (Dec. 13) at 4:40 p.m. ET about what we can expect from the video. Even better, you can preview the interview right this very second. Even better than THAT, you can watch a sneak peek of the video itself today on "The Big & Best Of 2012" live stream!

Looking effortlessly lovely in a purple-and-black shift dress and her signature red lipstick, Taylor provided some insight into what we can expect from her latest video in the preview clip (as well as hypothesizing why good girls go after bad guys): "I think it's an opposites attract kind of thing. I don't know that all good guys are only attracted to all bad boys. I think that everybody goes through phases as to what interests them. My favorite thing about [this video] is that this girl -- not only does she get sucked into this relationship with him, but she loses who she was before. And to her, that's the saddest part of losing him -- that she can't remember who she was before she met him." Oh, #SADZ! Well, color us even MORE intrigued.

Don't miss the premiere of "I Knew You Were Trouble." during "MTV First: Taylor Swift," airing on MTV December 13 at 4:40 p.m. ET.
