Who doesn't LUV Taylor Swift's surprise duets?!
The lovely ladiez got their adorbzie on while performing Ellie's hit Anything Could Happen!
It is seriously so cute to see these besties rock out on stage together like a couple little girls at a slumber party!
We mean, a couple little girls with mega talent!
After this performance, we certainly wouldn't turn down more music from these two together!
