The annual Global Citizen Festival kicked off in New York and it showcased some of the best acts in the world. The event was created by Coldplay frontman Chris Martin and seeks to end poverty across the globe by 2030.
It's certainly a pretty big and worthy cause so there's no doubt as to why Kendrick Lamar agreed to jump on the stage and absolutely tear it up!
The likes of Rihanna and Usher also joined Kendrick in the line up.
