Jennifer Lawrence recently laughed off a wardrobe malfunction while leaving the "Hunger Games: Mockingjay-Part 1" after party in London on Nov. 10. The 24-year-old actress reportedly almost suffered a nip-slip after her plunging neckline, dipped a little too much. However, instead of getting perturbed by the fashion faux pas, Jennifer pulled her dress together and carried on giggling with friend Lorde, who was sitting beside her in the car.

The actress wore a white cleavage-baring white gown for the occasion and coupled her look with minimal make-up and accessories. She opted for a risqué look only for the night gala, as during the world premiere in the morning, she was seen in a more covered up look, in a white Dior gown, featuring a closed neck.

During the event Jennifer also spoke about her co-star Josh Hutcherson. "It's really really hard acting with your best friend, because you have to pretend to be somebody else, and they are pretending to be somebody else. And you have to keep eye contact with them and be serious," she said, according to US Magazine.

Meanwhile, Jennifer has also sung a song in the film. It was reportedly the "Hunger Games" director Francis Lawrence who convinced, the actress to belt out a track written by the Lumineers. The song is called "The Hanging Tree" and it has been adapted from the Suzanne Collins' book.

Jennifer has also sung for the previous "Hunger Games" instalment, however, this time she was "horrified" to sing and "even cried" before lending her voice to the song, according to Radio Times' report. Francis says that Jennifer is not confident about her voice and is very sensitive about it. "The Hanging Tree" is mentioned in the Collins' book as the one taught to Katniss by her father. However, she is not allowed to sing it because of its disturbing lyrics.

The lyrics of the song go likes this, "Are you coming to the tree / Where they strung up a man they say murdered three." "Hunger Games: Mockingjay Part 1," is all set to release on Nov 21. The film stars Liam Hemsworth, Jennifer Lawrence, Hutcherson, Elizabeth Banks, Alexander Ludwig and others.
