It's no secret that Demi Lovato and Taylor Swift are not the best of friends anymore. However, fans are convinced Demi gave her fellow pop star some major side-eye during Shawn Mendes' performance at the 2018 Billboard Music Awards — and the moment was captured on camera.

In a three-second clip, Demi seemingly turns her head in Taylor's direction, where she is dancing with BFF Camila Cabello, before turning back to the stage and flipping her hair. TBH, if that's not shade, we don't know what is. Watch the video above to see Demi's shady look seemingly aimed at T-Swift.

Demi wasn't the only celebrity guest in attendance who was not impressed with Taylor's dance moves. Glee star Darren Criss tweeted about his obstructed view thanks to the "Shake it Off" singer. "Uh Miss…excuse me, Miss!" he said in the video. “Miss, I can’t see! I’m trying to watch Shawn Mendes?" He's officially our new favorite person.

This also wouldn't be the first time Demi has called out Taylor. In 2016, she slammed the blonde beauty for tearing down Katy Perry in her song "Bad Blood," which was supposed to be a feminist anthem. "Certain people could be doing more if they’re going to claim that as part of their brand,' she told Glamour magazine. "To be honest, and this will probably get me in trouble, I don’t see anybody in any sort of squad that has a normal body. It’s kind of this false image of what people should look like. And what they should be like, and it’s not real." Ouch.

More recently, the former Disney Channel star claimed a certain pop star was staying silent about politics — and all clues pointed to Taylor as the unnamed singer. "There are certain pop stars who don’t speak out politically, and they have more fans," she explained to Billboard magazine. "But I’d rather speak up for the things I believe in than just be dismissive of the issues going on in our country."

Seeing as Katy literally extended an olive branch to Taylor, we hope Demi will do the same.
