Jennifer Lawrence says she smoked weed on set to play a stoner in Netflix's 'Don't Look Up'

• Lawrence plays a weed-smoking astronomer in the upcoming Netflix movie "Don't Look Up."
• The actress admits to really getting high for a scene in the movie.

Jennifer Lawrence went method in her new movie "Don't Look Up," in which she stars opposite Leonardo DiCaprio as astronomers who try to warn the planet that a deadly comet is approaching Earth.

Starring as Kate, who smokes weed to calm her nerves, the actress admits she really got high during the filming of the movie to play the character.

"I know what you're going to say, and I wasn't pregnant [at the time]," said Lawrence, during a post-screening Q&A in Los Angeles Thursday night, via Yahoo.

In September, Lawrence announced she was expecting her first child with husband Cooke Maroney.

Director Adam McKay explained during the Q&A that Lawrence asked to smoke weed before doing a scene opposite Meryl Streep in which the "Hunger Games" star didn't have any lines. Streep plays the President of the United States in the movie.

"Because my character was getting high in the movie," Lawrence added.

"I was a real target," said Lawrence about the experience of being high on set. "Everyone was fucking with me, I guess because I was high. Easy to fuck with."

"Don't Look Up" also stars Jonah Hill, Mark Rylance, Timothée Chalamet, Tyler Perry, Ariana Grande, Cate Blanchett, Ron Perlman, Matthew Perry, Chris Evans, Melanie Lynskey, and Gina Gershon.

The movie will be in select theaters starting December 10 and on Netflix December 24.
