Jennifer Lawrence on Tonight Show - H 2012

Jennifer Lawrence says she was so excited about the thought of seeing Honey Boo Boo that she got into a car accident.

The actress, who next stars in Silver Linings Playbook, said on Monday's The Tonight Show With Jay Leno that she driving home from work one day while shooting The Hunger Games: Catching Fire when she passed a parade where she thought she got a glimpse of the 7-year-old TLC reality star and beauty pageant contestant, aka Alana Thompson.

"It was a breast cancer parade, and people were wearing [sashes] that said 'boobs,' but I thought it was saying 'Boo Boo,' and so I said, 'Whoa, does that mean Honey Boo Boo?" she told Leno. "So I started craning my neck and I saw a little girl and I was like, 'That's Honey Boo Boo.'"

Lawrence said she was still driving at the time and ended up rear-ending the car in front of her.

"I had to get out of the car and explain what happened," she said. "I was like, 'I'm sorry that I hit your family. I thought I saw Honey Boo Boo.'"
