The rapper, who took home five awards this year, performed a medley of his hits from his latest project, "Damn." With help from background dancers, who began the performance wearing Army fatigues, Lamar, 30, started off his performance by rapping, “XXX," in front of an American flag.
The words, "This is a satire by Kendrick Lamar," flashed behind him as he performed.
When comedian Dave Chapelle popped up onstage, many thought he signaled the end of Lamar's performance, but he was actually in on the act.
"Hi. I’m Dave Chapelle," he began. "And I just wanted to remind the audience that the only thing more frightening than watching a black man be honest in America is being an honest black man in America. Sorry for the interruption. Please continue.”
Lamar then concluded his six-minute performance, receiving a standing ovation and much praise online from celebrities.

"We come in peace, but we mean business," she began. "And to those who would dare try and silence us, we offer you two words: Time’s up."
