Sophia Grace and Rosie are freakin' PHENOMENAL!!
Not only can these two little British sensations sing Nicki Minaj and Adele's hits, but now they're taking on Taylor Swift's song, I Knew You Were Trouble, and we have to say, they KILLED everything about the singer's tune.
We don't know how they do what they do when they do it, but hearing these dolls sing their hearts out make us melt with nothing but joy.
Oh! And those tutus certainly added a plus to their fantabulous performance on their favorite stage on Ellen!!
