Watch Taylor Swift & Haim Perform 'Hot In Herre' With Nelly Live in St. Louis
Taylor Swift played the second of two shows at St. Louis's Scottrade Center last night (Sept. 29) and, well, things got a little heated -- in a good way.
Watch Taylor's snippets of their performance below, which include very careful choreography and emphatic singing to the song's unforgettable chorus. According to Taylor, it was "the highlight of [their] friendship thus far" (pretty understandable).
This isn't even the first time Taylor has invited the rapper on stage -- check out their 2013 duet of "Hey Porsche" below, as well as their 2011 (!) performance of "Just A Dream."
