Post Malone has been hitting the road on his “Welcome To The Zoo Tour.”

The 19-year-old paid his dues last night (February 9) in New York City, where he invaded Irving Plaza with tons of screaming fans.

Of course, the “White Iverson” vocalist had a few surprises up his sleeve, as he surprised the sold-out crowd by bringing out 50 Cent.

Malone and 50 ran through cuts from the Kanan Tape and even his hood classic “Window Shopper.”

Check out the footage from last night in the video clip below.
