Actress JENNIFER LAWRENCE lip-synced through a musical scene in upcoming movie HOUSE AT THE END OF THE STREET because she feared her singing voice was not good enough.

The Hunger Games star plays a young singer named Elissa Cassidy in the new horror film, and the script calls for her character to play the guitar and croon.

However, Lawrence was so nervous about how she'd sound, she asked the movie's music supervisor, Steve Lindsey, to hire a professional to sing the part so she could mime along.

He tells trade Variety, "Even (though) she was nervous, her humor about the situation shined through with her begging for us to 'Photoshop (edit)' her voice."

Session musician Sarah Rayne's voice was later dubbed over Lawrence's during post-production, fooling many film critics into thinking it was actually Lawrence they were hearing in the movie.
