Kanye West reportedly gets booed onstage at this year's Wireless Festival in the U.K., after treating fans with his latest rant.

The 27-year-old rapper paused in middle of his performance at London's Finsbury Park on Friday night, July 4, to preach against the his public image, social media and discrimination in the fashion industry. "People be looking at me like I got a problem or something," he began. "Like I'm uncontrollable, that I do what I'm not supposed to do."

West then complained about how media lies to people: "They control everyone with rumors and lies. ... They steal you from you and sell you back to you," before asking the audience, "How many people here think they're awesome and have had people say they're not their whole lives? What have I ever done other than believe in myself?"

The "Yeezus" rapper continued to express his frustration to the crowd, criticizing the fashion industry that previously rejected to do business with him. "I'm not going to mention any names but ... Nike, Louis Vuitton and Gucci. Don't discriminate against me 'cause I'm a black man making music," he said. "F*ck saving face and what it's supposed to mean, it's about living my dream."

In addition, West tried to encourage fans saying how determination worked for him. "I told Kim seven years ago, 'I'm going to marry you,' and I did," he revealed. "All the stuff I talk about, I can back it up."

"I want to change the world, and that's exactly what I plan to do," the Chicago emcee finally ended his rant that lasted more than 20 minutes, before launching into the second half of his set.

Consequently, fans lost their patience -- many of them leaving the venue early, and those who stayed booed the "New Slaves" rapper until he was done with his long speech. "He was laying into the 'machine' and ranting about the public's perception of him," a festivalgoer told Daily Mail. "Hundreds of people left the park early because they were so bored of his long rant. There was serious booing towards the end of the speech, as people got so fed up and just wanted to hear him perform."

Kanye West is set to headline again in London on Saturday evening, July 5, filling in for fellow hip-hop star Drake, who had to cancel his performance last minute due to his illness.
