Taylor Swift performs with HAIM and special guest Nelly onstage during the 1989 World Tour at Scottrade Center on Sept. 29, 2015 in St Louis, Missouri.

Previously, Swift had shared footage of the performance, along with the caption, "Yes we made up a dance yesterday in the dressing room."

Now we've got our proof.
