During her interview on "The Tonight Show," Gomez appeared to be in good spirits as she talked about "Monte Carlo" and also about how she obtained her driver's license six months ago. She said she has since gotten into an accident, hitting a pole with her car.
"I was very stressed and I reversed and I hit it," she said. "I was not texting, I was stressed. There were photographers following me so I got scared."
