The 23-year-old star, who was nominated for a Best Supporting Actress Academy Award for her role in 'American Hustle', was wasted at a post-show bash-and pop star Miley Cyrus witnessed the whole thing, reported Huffington Post.
Lawrence recalled having a little too much fun at this year's Oscars, which she attended with BFF Laura Simpson, on 'Late Night With Seth Meyers'.
"I was so drunk, I puked on the stairs at Madonna's after-party," she said.
At the after-party, Lawrence not only tossed her cookies at Madge's bash, but she did it in front of the Miley Cyrus, who told her to 'get it together'.
