Club management announced at about 1:45 a.m. that the rapper was not going to appear, causing the crowd to boo and throw items at the stage. Schaumburg police dispatched officers to the scene, but no arrests were made.
Snoop was in Chicago throughout the day, appearing at a press conference for his new youth football league, and at the Adidas store on Michigan Avenue later on in the day.
And according to numerous tweets and this blurry Twitpic photo, he also managed to hit the Fashion Friday event at Crimson Lounge after 11 p.m.
But as for the fans who paid up to $25 for his Schaumburg appearance? Barleycorn officials aren't sure if they'll try to reschedule the show.
Calls to Snoop Dogg's PR team were not immediately returned.
