Jennifer Lawrence appeared on David Letterman late night show. The interview tackled the promotion of the upcoming "The Hunger Games: Mockingjay - Part 1." However, as the interview continues, it turns into hilarious show.

J.Law admitted in hilarious way that "singing in front of other people" is her "biggest fear" by demonstrating her "tone-deaf Amy Winehouse voice" to the host.

She said, "I still haven't heard it. I put my fingers in my ears...I was like, 'Will you guys please get, like, Lorde to really sing it and I'll lip synch?' They said, 'No, it's really [got to be] your voice.' So, I avoid [watching] that scene."

E Online said that the reason why J.Law loathes singing in public is that she's already "scarred" from a childhood performance.

J.Law exlained "I have a mother-a Southern mother-who used to just tell me that I was amazing at everything, and I could do everything, but I can't, and this voice...I had when I was like 8, and so I sang in front of the school 'cause I was lik, 'I can do that! I can do anything!'"
"Have a Holly, Jolly Christmas"-and it was a disaster! "My dad laughed for like the entire week," she added.

After her appearenace on the late night show, there is a video obtained by ET whichs shows that Jennifer rushing inside the Ed Sullivan Theater in her red Antonio Berardi dress with a quick wave. Fans loudly booed the "Hunger Games" star.

When Jennifer starts signing an autograph, her bodyguard suddenly rushes her out of what appears to be a chaotic situation, and the 24-year-old actress hastily gets inside her vehicle.
