You know you've had a crazy night when Miley Cyrus tells you to pull it together. During an April 21 taping of NBC's "Late Night With Seth Meyers" (for an episode airing May 21), Jennifer Lawrence recalled having a little too much fun at this year's Oscars, which she attended with BFF Laura Simpson.

The 23-year-old "Hunger Games: Catching Fire" star, who was nominated for a Best Supporting Actress Academy Award for her role in "American Hustle," told Meyers she was "wasted" at the March 2 ceremony in L.A. She was so out of it, she said, that she got sick at a post-show bash -- and Cyrus witnessed the whole thing.

"Jen said she was so drunk, she puked on the stairs at Madonna's afterparty, and Miley walked by and said something like, 'Get it together, girl!'" a "Late Night" audience member shares in the new issue of Us Weekly.

Lawrence -- whose red carpet antics (such as falling and photobombing) have endeared her to moviegoers everywhere -- also shared a story about hanging out with Brad Pitt at the show. (Angelina Jolie's fiance was there in support of his Best Picture-winning movie "12 Years a Slave.")

"Jen said he smelled like sandalwood," the audience member tells Us of Lawrence, who lost to Pitt's costar Lupita Nyong'o. "She was so fun!"
