The singer, who opened the ceremony dressed as a circus ringmaster for a rendition of her hit We Are Never Ever Getting Back Together, seemed to change the words to her break-up track in reference to her split from the One Direction hunk.
Swift cheekily put on an English accent during the spoken part of the song, and instead changed the lyrics to say: "I'm sorry, I'm busy opening up the Grammys. We are never getting back together. Like, ever."
As well as appearing to make a dig at Styles, Taylor dazzled on the red carpet in a floor-length grecian style gown, complete with gold and cut-out detailing.
The 23-year old also took home the Grammy for Best Song Written For Visual Media at the bash for her tune Safe and Sound from The Hunger Games.
Swift and Styles are expected to come face-to-face with each other at The Brit Awards 2013 next week, where they will both take to the stage at London's O2 Arena to perform.
