Post Malone and Fetty Wap are currently in the middle of their "Welcome to the Zoo" tour, and with a stop in New York City last night, Post decided to make the most of the moment. And honestly, what better way to get a major pop in NYC than to bring out 50 Cent? Well, that's exactly what Post did last night, and as expected, the crowd went nuts when 50 touched the stage to perform a variety of his hits.

In particular, 50 ran through his classic cut "Window Shopper," which was an excellent choice since Post actually made his own remix of the song last year. Of course, they also performed their collaboration, "Tryna F*ck Me Over," which marked the first time that they've done the song together during a show. Overall, it was a pretty cool moment from 50 and Post that we hope turns into more new music together in the future. You can check out the rest of the dates for Fetty and Post's tour right here.
