For their appearance on "Ellen" the girls wore matching pink and white stripped tutu dresses, and princess crowns. Before their live performance Ellen showed footage of Sophia Grace and Rosie performing Swift's song in their hotel room.

Taylor Swift did not make a guest appearance, but the girls were adorable performing her hit single "I Knew You Were Trouble". Sophia Grace did all of the singing and Rosie danced a semi-choreographed routine that went along to the lyrics in the song.
