Kanye West has reportedly been booed at a London concert after launching into a 20-minute rant about discrimination in the fashion industry.

The 37-year-old star interrupted his act several times to complain, leading several people in the 50,000-strong crowd to voice their displeasure. However, Kanye ignored their heckling and continued to rave against the fashion world.

"I'm not dissing Luis Vuitton, I'm not dissing the Gucci group and s***," he said, according to RollingStone.

"I'm just saying, don't discriminate against me because I'm a black man or because I'm a celebrity and tell me that I can create, but not feel. 'Cause you know damn well there aren't no black guys or celebrities making no Louis Vuitton nothing."

"While the crowd cheered at first, they became tired and frustrated as the speech, which once again went on for 20 minutes with Kanye complaining that 'celebrities need to be allowed to have an off day as well'," says one insider.

"They began to boo with one section of the crowd saying 'We want Drake'."
