We've all been there. You're so lovestruck you're walking on fluffy clouds made of crushed-out feelings and your stomach is full of butterflies...
Turns out celebrities aren't immune to those mixed-up teenage feelings either. Check Taylor Swift, unable to contain herself, mouthing those sweet three words at her main squeeze Calvin Harris live in concert!
Aweee! They seem very happy with each other. When was the last time you just HAD to drop the "I love you" bomb?
Are Taylor Swift and Calvin Harris a cute couple?
