Rihanna showed up late to a planned appearance at Barrington High School in Chicago Friday after getting caught in a traffic jam. For four hours.
The 25-year-old was very late to greet students who won the contest she sponsored. She asked students to create videos showing their charitable work.
"On my way to Barrington High School in Chicago!" she tweeted Friday. "I can't wait to meet these kids man! They're major inspirational life changers."
But Rih didn't get to meet her young fans for awhile. "This Chicago traffic is not working," she tweeted with a picture of her car sitting in traffic.
