Rapper Kanye West has apologised for his comments about slavery, which found him at the center of controversy three months ago.

"I don"t know if I properly apologised for how the slavery comment made people feel," the 41-year-old said during a radio interview with WGCI Chicago. "So I want to take this moment right now to say ... I'm sorry for people who felt let down by that moment," he added, reported People magazine.
