Demi Lovato sure knows how to build up anticipation, because all this excitement is giving us a heart attack!
Ch-ch-check the last teaser (above)!
Ok, so we're not exactly sure what's going on here, but based on what we've seen from all three videos, we have a feeling it's all going to add up to be something awesome!
However, if these combined 38 seconds just aren't doing it for you, you're in luck! Because the FULL official music video for Heart Attack drops on April 9th!
We can't wait to see what Demi has in store for us!
