"It’s life…it’s right now. It’s happening right now. And what do I do? I go in and watch The Housewives of Beverly Hills. I do that,” she admitted.
Streep went on to joke that being able to watch The Real Housewives is her motivation for fighting climate change.
“When I saw the film, I was just blown away and I said [to director Adam McKay], 'Give me a checklist. Give me the first three things we have to do,'" she continued. "It’s so energizing in a weird way, this film, because you come out and you go, 'OK now, f**k it. This is what we have to pay attention to. It all flows from this. If we don’t survive, we won’t be able to watch Housewives or whatever.'"
The drama sees Lawrence as astronomy grad student Kate Dibiasky and Leonardo DiCaprio as her professor, Dr. Randall Mindy, teaming up after discovering that a comet is going to hit earth. The two then embark on a giant media tour to warn mankind of an approaching comet -- but not many people seem to care, including the president of the United States, played by Streep.
ET spoke to Lawrence at the film's premiere in December where she had nothing but praise for her three-time Academy Award-winning co-star.
"I mean, Meryl Streep is the actual greatest actor that has ever lived, and when you watch her in person it only confirms that," Lawrence marveled.
