Now this is how to celebrate a birthday party!!
Of course, this wasn't the first time Tay and Nelly have joined up for a memorable musical experience!!
The Shake It Off singer and the Hot In Herre rapper got together for an impromtpu collab, and lucky for all of us, it was caught on camera for the rest of the world to enjoy even beyond the birthday bash!
Ch-ch-check out the two of them paired up for some performances to celebrate birthday boy and oil heir Mike Hess (below)!!!
