The sisters of HAIM did their last show on Taylor Swift's 1989 Tour on Tuesday night in St. Louis, and they went out with a bang. The latest in Tay's insanely long list of high-caliber guest stars was Nelly, and the joy that came with the collaborative performance of "Hot in Herre" was real.
Yup. You just witnessed Taylor Swift and HAIM doing that "I think my butt gettin' big line." On Instagram, Tay revealed that the ladies "made up a dance in the dressing room." (Plus, of course, that tweet's line that this was "the highlight of our friendship thus far.")
