Jennifer Lawrence stopped by the Late Show With David Letterman on Wednesday to promote The Hunger Games: Mockingjay — Part 1 and gave the world a treat — sort of.

The Kentucky native stole the show by singing with Letterman in a rendition of Have a Holly Jolly Christmas.

The song came about after Lawrence shared about having to face her fear of singing in public while filming the highly anticipated movie. In the film, her character, Katniss Everdeen, sings The Hanging Tree to a Capitol cameraman, bringing him to tears.

“I do not like singing in front of other people, that’s like my biggest fear,” she told Letterman. “I cried on set that day. I’m scarred from my childhood.”

The 24-year-old actress, who recently said she’ll never join Twitter, admits that singing is not her forte. She told Letterman that since she was eight years old, she possessed a “tone-deaf Amy Winehouse” voice that her parents made fun, all the while telling her how great she sounded.

“I have a Southern mother that used to tell me I was amazing at everything and I could do everything, but I can’t,” she said. “I had this tone-deaf-Amy-Winehouse voice and I sang in front of the school when I was eight, because I thought I could.”

After filming both installments of Mockingjay at the same time, she took some needed time off. However, Lawrence admits that too much time off was not necessarily a good thing.

“I took some time off. I lost my mind. It was awful,” she said. “I don’t even know how crazy I went.”
