*Lauryn Hill is apologizing to her fans in Chicago who came out to see her perform on tour with Nas, only to experience some technical difficulties during her set.

The former Fugees star was at Chicago’s Congress Theater last night, where sound troubles marred her performance so much that she took to Twitter to apologize.

“Chicago! We had some serious technical difficulties tonight that compromised our sound. We apologize, and will be back soon. Love you,” she wrote.
