Singer-songwriter Chaka Khan, honored in Chicago with a street named for her, said her hometown is "extremely racist" but has "much to offer."

The 10-time Grammy winner was scheduled to headline a free concert in Millennium Park Sunday, one day after the city named a South Side street "Chaka Khan Way," WBBM-TV, Chicago reported.

"I can't believe my name is hanging there under Blackstone (Avenue)," Khan said, as she celebrated her 60th birthday and her 40th year in the music industry, the report said.
