Although Jennifer Lawrence is one of the biggest -- and seemingly one of the most confident -- stars in Hollywood, even she admits to having insecurities after coming out of a longterm relationship.

In a new interview with Diane Sawyer, the 25-year-old Oscar-winning actress gets candid about having to come to terms with the end of filming on The Hunger Games series last year, which just so happened to coincide with her breakup from her X-Men: Apocalypse co-star, Nicholas Hoult.

"These movies had been my life for so long and they had to come first in everything," Lawrence says. "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."

"Being 24 [years old] was this whole year of, 'Who am I without these movies? Who am I without this man?'" she shares. "It was always 'we.' It sounds so young to say that but it's true."

These days, Lawrence isn't even sure if she plans on ever getting married.

"I don't feel like I need anything to complete me," she explains. "I love meeting people -- men, women, whatever -- I love people coming into your life and bringing something. I don't really plan on getting married. I might. I definitely want to be a mother. I don't really imagine getting married anymore."

However, this appears to contradict what the Joy actress recently told Vogue, saying she "can't wait" to walk down the aisle.

"I can't wait to be married," Lawrence surprisingly told the magazine. "I feel like if I find that one person who I want to spend the rest of my life with, who I want to be the father of my children, that I would absolutely not f**k it up."

"But I'm also not banking on that," she added.

Whether she decides to tie the knot or not,  Lawrence is clearly just fine on her own. The actress is still speaking up for women when it comes to Hollywood's gender gap.

"I felt like I had had to say something because we need to talk about it," Lawrence said about her widely-praised essay after it was revealed that she was paid much less than her male co-stars for American Hustle. "My question to myself was, 'Why am I not asking for it?' And I think I know I have always kind of carried a habit of submissiveness with the idea that it makes me more likeable."

"On average women are paid 21 percent less than men," she points out. "We can ask for the same exact thing that men do and ... we do face the reality that we do get judged more. If we’re harsh, we get judged more ... It’s just something that is intrinsic and I would love to see change."
