Lawrence, who has become a household name as a part of huge franchises like "The Hunger Games" and "X-Men," has worked to balance her professional life with her personal life as best she can.
Of her relationship with Nicholas, she revealed, "These movies had been my life for so long and they had to come first in everything. I was also in a relationship with somebody for five years and that was my life. So my life was this person and these movies and we broke up around the same time that I wrapped those movies." Watch a clip of the interview!
She added, "Being 24 was this whole year of, 'Who am I without these movies? Who am I without this man?'"
Jennifer, who is currently single, has a hard time imagining herself as a married woman. "I don't know if I ever will get married and I'm okay with that. I don't feel that I need anything to complete me. I love meeting people, men, women, whatever, I love people coming into your life and bringing something."
She doesn't see marriage in the future, but she can imagine herself as a mother. "I don't really plan on getting married. [But] I definitely want to be a mother. I don't really imagine getting married anymore."
