Yesterday, during the 2018 Billboard Music Awards, fans have accused Demi of being completely unimpressed with Shawn Mendes' performance of his new hit single, "In My Blood".
While performing the song, the camera pans to Demi, where you can see her looking off to the side uninterested, while flicking her hair over her shoulder.
Girl was not feeling it.
Other people seem to believe that maybe Demi was getting pissed off with Shawn's groupies - Taylor Swift and Camila Cabello - dancing around to support him during his song.
We also know that Demi can be the victim of a bit of resting bitch face, and we're sure she really does love Shawn and his singing.
