The film, which stars Colin Farrell, Josh Hutcherson and Christoph Waltz, tells the story of a teenager, who is transported into a secret forest world then embroiled in a battle between good and evil and has to protect a special flower pod to save the forest.
The 31-year-old singer said that there was a scene where her movie character Queen Tara picks out her pod and she just imagined seeing her child, the Mirror reported.
The former member of Destiny’s Child said that she was attracted to the film because of the message and as she was about to give birth to her child.
She asserted that she was pregnant when she first went to the studio and she thought that the film will be something that would leave a legacy for her daughter.
She added that the character had so much heart and emotion and she was so filled with emotion and hormones that she literally cried in some scenes.
