The claws are out, Swifties! Just when everyone seemed to be getting along so well, Taylor Swift went up on stage to accept her award for Artist of the Year and everyone stood up and cheered on the "Sweeter Than Fiction" star except for one person — Miley Cyrus' sister, Brandi Cyrus!
Miley's dad got up like the rest of the audience, but Brandi stayed seated, looking at Taylor like she didn't want anything to do with her big win. We're not sure what's going on between them — especially since Taylor even mentioned Miley's awesome performance while accepting her award — but it looks like things are about to be pretty awkward from now on.
Do you think it was rude of Brandi to diss Taylor while she was accepting her award? Let us know in the comments!
