During the spoken part of "WANEGBT," Taylor put on her best British accent and in just a blink of an eye, both confirmed that she and Harry had broken up for good and also got a dig in on the One Direction hottie.
Let's just say Harry's fans weren't too happy with Taylor's little stunt.
Twitter lit up with plenty of Taylor hatin', calling her out on the choice to diss Harry in such a public way.
One tweet read, "Why did Taylor have to do that. It's pathetic. Your 23 years old. You humiliated a 19 year old in front of everyone. Uncalled for. Grow up."
Overall, most Harry fans thought Taylor was totally disrespectful to Harry and immature, but since she doesn't have a new song out that burns her ex, she probably figured the Grammys were as good a place as any to make her feelings known.
