The actress, who plays protagonist Katniss Everdeen in the blockbuster, showed off her flawless hourglass figure in the sassy dress, flaunting her ample cleavage and perfect pins.

Jennifer wore her hair in a chic combed-back ‘do, and kept her make up glam with a slick of dark eyeliner and a shiny lip.

Fans turned out in force for the world premiere of the Hunger Games: The Mockingjay part 1 at the Odeon, Leicester Square on Monday night.

Stars including Liam Hemsworth, Josh Hutcherson, Juliane Moore and Donald Sutherland joined the stunning actress on the red carpet at the blockbuster’s release.

“We are so thrilled by the reception of these movies from all the fans around the world,” the actress said.

The film is the third instalment of the Hunger Games trilogy, based on part 1 of the best-selling third novel by Suzanne Collins.

Having twice survived the vicious Hunger Games, the film follows Jennifer, who plays, Katniss Everdeen, as she reluctantly becomes the symbol of a mass rebellion against the autocratic Capitol which wants its retribution.

The film is the first of the hunger games movies to be directed by Francis Lawrence, and is expected to rake in more than $155 million at the box office.

The film will feature some of the final scenes from Philip Seymour Hoffman. The actor died in February before filming had ceased.
