McDonald's USA has pulled Chicago-based rapper Twista from appearing on its free 10-city parking lot tour, citing the hip-hop artist's "controversial lyrics."

Twista was scheduled to perform Aug. 7 in Chicago as part of the multi-genre McDonald's Live jaunt, which started July 26 in Venice, Calif., and continues through Sept. 25 in Austin, Texas. Negotiations are still pending for a replacement headliner in Chicago, the fast food giant says.

"Although we respect free speech and artistic expression, we do not condone or perpetuate derogatory language," McDonald's USA said in a statement. "We want to ensure these free concerts are fun as well as appropriate for all of our customers."

Representatives for Twista were not available for comment at press time.

As previously reported, McDonald's Live, a collaboration between McDonald's and event marketing agency TBA Global, visits such markets as Denver (Single File), Philadelphia (Kevin Michael) and Bloomfield, N.J., (Kat DeLuna, the Dey). The majority of dates will be held in McDonald's parking lots around the country.
