The Ready For It? wasn't expected to make an appearance during the night's proceedings so she shocked fans when she made a surprise appearance in a video tribute to Diana Ross, who is being honored with this year's American Music Award for Lifetime Achievement.
"Hey Diana, it's Taylor. I just want to say congratulations on your lifetime achievement award I want to say congratulations. I don't know anyone who hasn't been inspired by you. You're elegant, fierce, strong, and brave, and you have paved the way for everyone who does what we do now. Including me. So, thank you," Swift gushed in the pre-recorded video.
