Jennifer Lawrence has been hem...vocal...about her fear and dislike of singing in public. Well, singing in front of anyone. She did what she did NOT want to do in the "Hunger Games: Mockingjay Part 1" and thought it was all over. It's the opposite.

I can't even imagine the panic that Jennifer Lawrence must be feeling at this moment. Her son "The Hanging Tree" from the movie could hit the top 40 charts. As in: It could be on the radio! OMG! I would die!

From the sounds of her interview with David Letterman, Jen might, too. See the interview and listen to her song below.
