Getting to see Jay-Z for free is all fun and games until someone gets stabbed.
Thatís what happened at the House of Blues last night, according to cops.
When the concert ended a pair of girls got into an argument, said Police News Affairs Officer Gabrielle Lesniak. Then their men got involved --- one a brother, one a boyfriend.
The men started shoving each other. One then pulled a knife and stabbed the other, a 20-year-old man. Jay-Z was not performing at the time.
The stabbing victim was taken to Northwestern Memorial Hospital in good condition. The stabber was taken into custody. Charges are expected later today.
