Jennifer Lawrence's real-life nephews played her children in the final scenes of The Hunger Games franchise.

The actress invited her film fan relatives to the set as she wrapped up her time as Katniss Everdeen, and the youngsters were asked to be part of the shoot.

"Having my nephews on the set was so special," she tells WENN. "They played my children, so it was an amazing closure to this character who I loved for so many years, to have my blood family there.

"I got to say goodbye to both; but I don't really think I said goodbye to her (character of Katniss). When the movie comes out and we finish the press tour and it's officially done, that's gonna be a pretty weird feeling on a personal level. This movie has been my life for so many years. I feel the impact of being a part of such a huge movie that does so much for so many people.

"This character is so overwhelmingly supportive of women and is iconic."
