Oprah performed with Black Eyed Peas on Sept. 8 in Chicago while taping an episode of "The Oprah Winfrey Show" on a three-block stretch of Chicago's Michigan Avenue.
The daytime diva has already paid the bill for the impossible-to-miss season premier party that shut down Michigan Avenue for two days this month.
Within 24 hours of receiving the $54,832 bill, the city was able to mark it paid in full.
"They had the checks cut and delivered this morning," Cindy Gatziolis, a spokeswoman for the city's office of Special Events, told the Sun-Times Friday. "That's pretty quick."
Here's a breakdown: $28,277 went to the Office of Emergency Management and Communications for traffic control between Sept. 7-9; $12,014 to the Chicago Police Department for off-duty officers; $7,075 to the Fire Department for "safety officers"; $6163 to the Bureau of Electricity to "remove traffic signals" and $1306 to the Department of Streets and Sanitation to cover the barricades.
No word on the tip.
