Rihanna needs an alarm!

Four minutes late? No big deal. Four hours late? Not OK! Rihanna was supposed to meet with students form Barrington High School in Chicago, Illinois, who won a contest she sponsored, but she was caught in a serious traffic jam. Luckily, Riri's fans are the coolest and didn't mind waiting that long to meet her. But next time, we hope she sets an alarm and arrives early!
