The '1989' tour got a VERY exciting special guest this week - Taylor almost couldn't believe it!

Taylor Swift and Haim pretty much got to fulfil a life-long dream last night - performing live as Nelly’s backing dancers!

Yep - for her latest ‘1989’ tour guest Taylor managed to bag the rap star, who showed up to her gig in St. Louis, Missouri to perform ‘Hot In Herre’ for all the #Swifties in the house.

Taylor and the Haim ladies were clearly loving LIFE throughout the performance - showcasing their original and perfectly choreographed dance moves. AMAZING!

“The highlight of our friendship thus far @HAIMtheband,” Taylor posted after the show. “PS WE LOVE YOU @Nelly_Mo.”
