During her record-breaking Staples Center concert last night, (Taylor has performed there more than any act ever) she invited Tegan and Sara up to perform "Closer" with her!
The video moves away from the big screen before the first minute for some fab footage!
We have been on "Closer" since it came out and it is still going strong! Check out the performance above.-DocFB
Diagnosis: We have a feeling Taylor wishes she wrote this song.
