Jennifer Lawrence may be a natural when it comes to acting, but singing is apparently a whole different story.

The Academy Award-winning actress broke down in tears before singing in the latest Hunger Games installment, her director said in a recent interview with Radio Times. “She’d probably tell you it was her least favorite day,” said Francis Lawrence. “She was horrified to sing, she cried a little bit in the morning before she had to sing.”

Though J-Law has performed songs for other movies, including a lullaby in the previous Hunger Games film, she apparently remains uncomfortable with her voice. “We had a vocal coach, who sort of shifted the key for Jen’s voice,” the director added. “Then she started working with Jen once or twice… Jen didn’t really want to do too much of the training.”

The Hunger Games: Mockingjay Part 1 opens in theaters on Nov. 21.
