Demi Lovato will perform "Give Your Heart A Break" at the 2012 MTV VMAs Pre-Show, and WE. CAN'T. WAIT.

Lovatics, you may want to take a deep, cleansing breath for this. In addition to making 20th birthday kissy faces with Kim Kardashian, earning a 2012 VMA nod in the "Best Video With A Message" category, and just generally being, oh, I don't know, the ultimate role model and OUR FAVORITE WOMAN ON THIS PLANET, Demi Lovato will perform "Give Your Heart A Break" LIVE at the 2012 MTV VMA Pre-Show! (As in "Give Your Heart A Break," as in the perfect pop song, remember?) So make sure you're glued to your TV Sept. 6 at 7pm -- 'cause that's when Demi starts breaking hearts. ::Setting phone alarm...NOW::

Oh, yeah, and you didn't think we'd leave it at that, right? Because why would we stop there?? Please tell us you already know that once the big show starts, Taylor Swift, Green Day, Pink, Alicia Keys and One Direction will perform, PLUS Miley Cyrus, Wiz Khalifa, Mac Miller and the “Fierce Five,” and the U.S. Women’s Olympics Gymnastics Team will each help present Moonmen. I'm fainting -- PLEASE, one of you, revive me in time for the VMAs!

Don't miss the 2012 MTV VMAs live from Staples Center in Los Angeles on Thursday, Sept. 6, at 8 p.m. ET/PT.
