We can’t believe we missed this! Nelly made a surprise appearance at Taylor Swift’s concert in St. Louis on Tuesday, Sept. 29, and performed his 2002 hit “Hot in Herre” with the pop superstar.

The “Wildest Dreams” singer, 25, surprised fans when Nelly, who has called St. Louis home, walked onstage. Along with Haim, who have opened on Swift’s 1989 tour since the summer, the rapper, 40, and Swift also performed Nelly’s new single, “The Fix.”

And in true Swift fashion, the superstar shared two videos and a photo from their “Hot in Herre” collab on Instagram.

“Yes we made up a dance in the dressing room,” captioned Calvin Harris’ girlfriend in one of the videos, which showed the rapper, three Haim sisters — Este, Alana, and Danielle — and Swift performing.

“Old friends. @derrtymo [Nelly] has come out to surprise the crowd on my last 3 tours,” noted Swift in her caption. “I absolutely adore him.”

Nelly also shared a video of the two of them performing his new single. “STL CRAY tonight my sister @taylorswift and myself killed #THEFIX…!!!!” Swift sang the hook on his song.

Of course, as Swift has documented comprehensively on her Instagram, a staggering array of A-list stars have already joined Swift onstage throughout her massive tour, including Julia Roberts, Steven Tyler, Mick Jagger, Joan Baez, Karlie Kloss, and Lena Dunham.
