You know him for his popular books "The Fault in Our Stars" and "Paper Towns", but John Green has a new job.
The Indianapolis native will drive the pace car at the Angie's List Grand Prix next month.
Green got to take some practice laps around the track Sunday in the corvette.
He says he's always been a big Indy Car fan, and it showed on Sunday.
"I also got to go around the oval with my wife," said Green. "She looked over at me at one point and said, 'Are you crying?' And I said, 'A little'."
The Grand Prix road course race is May 14.
