Ariana Grande took to the stage at the 2015 Grammy Awards to perform her ballad 'Just A Little Bit of Your Heart' and, like always, her vocals were totally on point. The song -- penned by the ever-hopeless romantic, Harry Styles -- is a super sweet one, though also insanely depressing when you consider the lyrics.

Don't believe us? We'll break it down for you. The lyrics include, "I don't ever ask you where you've been / And I don't feel the need to know who you're with / I can't even think straight, but I can tell / That you were just with her / And I'll still be a fool / I'm a fool for you." Ouch. Loving someone even when you know their heart belongs to someone else? Talk about painful.

And after the super high-energy performance from AC/DC, it was nice to slow things down a bit and be able to focus solely on Ariana and the music. She looked gorgeous, too, with an expertly drawn cat-eye, soft pink lips and her signature slicked-back ponytail.

What did you think of Ariana's performance? If you missed it, you can check it out in the video above! Does it make your eyes well up with tears? Are you wondering who inspired Harry to write the track? Are you wishing it was you? Because same.
