Taylor Swift is known for pulling out all the stops during her live shows and her Red tour will certainly be no different! Her last tour 'round the world, she got into the habit of covering a song of a famous artist from every city she stopped in. Now it looks like T. Swift is raising the stakes!

At her latest stop in St. Louis, the '22' songstress brought out one of the city's more prominent musical figures, none other than Nelly! The St. Lunatics ringleader launched into a performance of his country-fied new single 'Hey Porsche,' with a little accompaniment by Swift herself!

The two superstars worked the stage and the crowd like the consummate pros they are. We must admit we were a bit disappointed Nelly didn't launch into one of his classics like 'Country Grammar' or that his St. Lunatics didn't make an appearance. Seriously, does Murphy Lee really have that much going on?

Swift played a gracious hosted asking the crowd, "How much do you love Nelly?!" At the end of the song, the two unlikely buds embraced and skipped off the stage together in total bliss!

We're just going to say what you're thinking... Nelly and Taylor Swift collaboration ASAP! Please and thank you!
