Jennifer Lawrence and Darren Aronofsky split up after dating for almost a year, and the Hunger Games actress has finally revealed what led to their breakup.

Lawrence opened up about her split with the director to Adam Sandler during a sit-down interview with Variety Studio's Actors on Actors series.

"Normally, I promote a movie, you put the work in to promoting it, ask people to go see it, and then it's just kind of out of your hands. I normally just kind of let it go," the Oscar-winning actress said and pointed out that Aronofsky would do just the opposite.

Lawrence worked with Aronofsky in the movie Mother!, and the couple split up after the movie came out. She explained to Sandler, "We'd be on the tour together. I'd come back to the hotel, and the last thing I want to talk about or think about is a movie.

"He [Aronofsky] comes back from the tour, and that's all he wants to talk about and I get it. It's his baby. He wrote it. He conceived it. He directed it," she said of the director's habit that eventually led to the separation.

"I was doing double duty trying to be a supportive partner while also being like, 'Can I please, for the love of God, not think about Mother! for one second?'" she continued.

Lawrence revealed that she found it unhealthy when the director would start reading some of the reviews they received for the movie. "I finally was just like, 'It's not healthy. Neither of us are doing it because if I read it, I start getting defensive.' Especially because it's my man.

"I don't want to sound in an interview that I'm defending what we're doing in any way. It's awesome, what we did. Some people hate it and the people who hate it really hate it. But it's nothing that needs to be defended and if I read a negative review, I just feel defensive," the actress added.

Lawrence previously told Entertainment Weekly she wasn't surprised by the divisive audience reaction to her psychological horror film, which received the infamous F CinemaScore.

She admitted, "There is no middle ground. We knew that it was divided. That's what [was] so exciting — everybody is going to feel something. It's going to create a conversation. It's going to create a controversy. Nobody is going to leave not getting something from it."
