Watch Taylor Swift, Nelly and Haim Perform 'Hot in Herre' in St. Louis

With Taylor Swift out on tour, expect two things: All-star guests making surprise appearances – just this weekend, she welcomed Steven Tyler and Mick Jagger to the stage – and Nelly coming out for her St. Louis shows. Swift’s 1989 Tour descended on St. Louis Tuesday night, and as is tradition, Nelly was on hand at the Scottrade Arena to perform to his hometown crowd. The rapper delivered his 2002 smash “Hot in Herre” with Swift and the Haim sisters serving as Nelly’s dancers and backup singers.

Nelly also performed his latest single “The Fix” with Swift before the “Hot in Herre” dance party. As Billboard points out, this is the third time Nelly and Swift have appeared together onstage: During the singer’s 2013 RED Tour stop in St. Louis, she and Nelly did a duet of his then-new single “Hey Porsche,” and in 2011, the pair sang his “Just a Dream” together during Swift’s Houston concert; when Nelly wasn’t around for Swift’s 2011 St. Louis gigs, she performed “Just a Dream” live on her own.

Tuesday night’s concert also marked Haim’s final date as Swift’s opening act, so she arranged the “Hot in Herre” sing-along as a thank you to her buddies, the singer tweeted. Recent 1989 shows have seen Swift welcome artists like Dierks Bentley, Lisa Kudrow, Natalie Maines, Sam Hunt, Beck and St. Vincent to the stage, along with an star-studded Nashville run this past weekend that featured Mick Jagger, Leona Lewis, Steven Tyler and Alison Krauss.

Swift’s 1989 World Tour will conclude its North American leg with a Halloween night concert in Tampa Bay, Florida. After that, Swift will embark on a jaunt through Asia and Australia.
