Adorable UK duo Sophia Grace and Rosie returned to the United States this week to once again appear on "The Ellen DeGeneres Show" -- and this time, they tackled Taylor.
The two, who became an Internet sensation in September 2011 with a viral video of them performing Nicki Minaj's "Super Bass," are apparently still a thing and performed Taylor Swift's "I Knew You Were Trouble" today on the show.
And we've gotta say, it's one of Rosie's best performances yet.
While Sophia Grace still sang the entire song, her silent costar was definitely more into her moves this time around. She must really be a Swift fan!
Check out the video above -- do you still love these girls a year and a half later?
