Some things never change! Taylor Swift [2] made a surprise appearance at the Billboard Music Awards [3] on Sunday night and immediately reverted back to her old award show ways as she sat with Camila Cabello and Shawn Mendes. While host Kelly Clarkson performed a melody of this year's biggest hits [4], Swift couldn't help herself from singing along to her track "Look What You Made Me Do."

It was certainly a big night for the singer. Aside from sharing some adorable moments with celebrities, she also took home two major awards [5] during the show, including top female artist. Rewatch her adorable reaction to Clarkson's medley below.
